Dynamic "Top" List

I am building a visualforce page based on Idea standard object components. I need to display the 2 most recently submitted ideas (Title, Name, Date), 2 with the most votes (Title, Name, Date), and the top 6 contributors based on number of submissions. I'm sure there is a way to do this with SOQL, but am not too sure about the syntax.

If I understand it correctly, I plug this all in my controller, then call it from my visualforce page?

Thanks for any and all help!

In that case this is the vf you need,
<apex:page controller="topIdeaExt">
    <apex:pageBlock title="Recent 2">
        <ul>
        <apex:repeat value="{!Recent2}" var="r">
            <li>
                <ul>
                    <li>
                        <label>Title</label>
                        :<span id="title"> <strong>{!r.Title}</strong> Util</span>
                    </li>
                    <li>
                        <label>Date</label>
                        :<span id="date"> <strong>{!r.CreatedDate}</strong></span>
                    </li>
                </ul>
            </li>
        </apex:repeat>
        </ul>
    </apex:pageBlock>
    <apex:pageBlock title="Most Voted 2">
        <ul>
        <apex:repeat value="{!MostVoted2}" var="r">
            <li>
                <ul>
                    <li>
                        <label>Title</label>
                        :<span id="title"> <strong>{!r.Title}</strong> Util</span>
                    </li>
                    <li>
                        <label>Date</label>
                        :<span id="date"> <strong>{!r.CreatedDate}</strong></span>
                    </li>
                </ul>
            </li>
        </apex:repeat>
        </ul>
    </apex:pageBlock>
    <apex:pageBlock title="Top 6 Contributors">
        <ul>
        <apex:repeat value="{!Top6Contributors}" var="r">
            <li>
                <ul>
                    <li>
                        <label>Name</label>
                        :<span id="title"> <strong>{!r['Name']}</strong> Util</span>
                    </li>
                </ul>
            </li>
        </apex:repeat>
        </ul>
    </apex:pageBlock>
</apex:page>

I took the liberty to add one nested ul. Modify/Add more fields as per your need. Note the usage of apex:repeat. You can generate any html element as per your requirement.

Hi

Use this,
<apex:page controller="topIdeaExt">
    <apex:pageBlock title="Recent 2">
        <apex:pageBlockTable value="{!Recent2}" var="r">
            <apex:column value="{!r.Title}"/>
            <apex:column value="{!r.CreatedDate}"/>
        </apex:pageBlockTable>
    </apex:pageBlock>
    <apex:pageBlock title="Most Voted 2">
        <apex:pageBlockTable value="{!MostVoted2}" var="r">
            <apex:column value="{!r.Title}"/>
            <apex:column value="{!r.CreatedDate}"/>
        </apex:pageBlockTable>
    </apex:pageBlock>
    <apex:pageBlock title="Top 6 Contributors">
        <apex:pageBlockTable value="{!Top6Contributors}" var="r">
            <apex:column value="{!r['Name']}"/>
        </apex:pageBlockTable>
    </apex:pageBlock>
</apex:page>
public with sharing class topIdeaExt {
    public List<Idea> getRecent2()
    {
        return [SELECT Id, Title, CreatedDate FROM Idea order by createdDate desc Limit 2];
    }
    public List<Idea> getMostVoted2()
    {
        return [SELECT Id, Title, CreatedDate FROM Idea order by VoteTotal desc, CreatedDate desc Limit 2];
    }
    public List<AggregateResult> getTop6Contributors()
    {
        return [SELECT CreatedById, CreatedBy.Name Name  FROM Idea group by createdbyid, CreatedBy.Name order by count(CreatedById) desc limit 6];
    }
}

Thanks for the reply! However, I am not using the Salesforce standard styles. I already have a html page already coded out. I have areas where I want the Salesforce results to appear. Here is where I would need the it to appear in the html:

<ul>
                                        <li>
                                            <label>Title</label>
                                            :<span id="title"> Stuff Util</span></li>
                                        <li>
                                            <label>Username</label>
                                            :<span id="username"> Chris Brown</span></li>
                                        <li>
                                            <label>Status</label>
                                            :<span id="status"> Active</span></li>
                                        <li>
                                            <label>Date</label>
                                            :<span id="date"> 1/19/2014</span></li>

The bolded areas are where I would like them to appear as a separate instance. This would not be in a table form.

Thanks again!

Thanks for all you help so far. I've plugged in your code and it works well until I add a second record. I don't think I need the repeater component. Here is a further snippet of my html so far:

<div> 
                                    <apex:pageBlock >
                                    <img src="{!URLFOR($Resource.Cost_Center, 'images/person_image.png')}" width="75" height="75" alt="costcenter"/>
                                        <ul>
                                        <apex:repeat value="{!Recent2}" var="r">
                                        <li>
                                        <ul>                                      
                                            <li><label>Idea Title</label>
                                                :<span id="title"> {!r.Title}</span></li>

 I just want the number 1 record data to fill in the first section and the number 2 record data to fill in the second section. Everything is already pre-formatted. The first section fills out nicely, but I don't want the second record to "repeat" after it. I want it in the second section provided in the html. 

Thanks again!

I got it to work! After moving around the <apex:pageBlock> and <apex:repeat> tags, I got the data and the formatting to repeat nicely!

Thanks so much!!
