Try it like this:

 

public Boolean showInput { get; set; }

public YourClassName(){
    // Hide input by default
    showInput = false;
}

public PageReference(){ 
    // Here comes your logic
    ... 
    // And setting the flag to true 
    showInput = true; 

    return null; 
}

 

And the visualforce page:

 

 

<apex:commandButton action="{!addWhatYouWant}" value="Add" reRender="myInput"/>

<apex:outputPanel id="myInput">
    <apex:outputLabel value="AssignedTo3" for="AssignedTo3" rendered="{!showInput}"/>
    <apex:inputField id="AssignedTo3" value="{!tsk.Assigned2_To__c}" rendered="{!showInput}"/>
</apex:outputPanel>
