You could either load the response from an ajax call inside a div or use an iframe. It looks like wikimapia itself uses an iframe wrapped inside a div.

<style>
#iframe_wrapper{
    position:absolute;
    top:20px;
    left:50%;
    margin-left:-150px;
}
</style>
<div id='iframe_wrapper'>
    <iframe src='http://www.google.com'></iframe>
</div>
