Forum:Showing only NewPages and nothing else on page ?

I want to show a little window with

on the main page of my vbulletin forum. I found out I can use a simple iframe to transfer the code from wiki to vbulletin (or any other html page for that matter) like this http://www.w3schools.com/TAGS/tryit.asp?filename=tryhtml_iframe

So what I need is an "empty" window only containing the NewPages or RecentChanges - no menus or headlines or anything else. Help much appreciated. Thanks!

If noone can help, perhaps someone can recommend a coder that can do it?
