I would change sendEmail method to return Boolean value. And then in custom button js definition based on result == true | false you can display some information to the user. The easiest but not very elegant way would be to use JS alert. If this is a VF page you can quite easily create some section with result info and fill it with JS

Ok, sure. As mentioned in my previous post I don't know exactly how would you like to present this message to the user so I will just use the simpliest way (JS alert). Here is modified controller:
global class SendEmailController {

    webservice static Boolean sendEmail(id oppid){
        if (MY IF CONDITION){   //MY IF CONDITION
            System.debug('**********T.ownerid');
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            mail.setTargetObjectId(Ownerid) ;
            mail.setWhatId(oppid);
            /*
               MY OTHER LOGIC
            */
            Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
            return true;
        }
        return false;
    }

and your custom button definition with JS alert:
{!REQUIRESCRIPT('/soap/ajax/29.0/connection.js')}
{!REQUIRESCRIPT('/soap/ajax/29.0/apex.js')}
document.location.reload(true);

var result = sforce.apex.execute('SendemailController','sendEmail,{oppid:'{customobject__c.Id}'});

if (result) {
    alert('success');
} else {
    alert('email not sent');
}
