you can use javascript window.showModalDialog function. It will show any web page in a modal window. i.e
var winSettings = "center:yes;resizable:no;dialogHeight:300px";
var myArgs = null;
window.showModalDialog("http://www.google.com", myArgs, winSettings);

Note: Just remember that cross browser issue is there.
I found Major browsers like Safari, Firefox, IE it is working.
But it is not working in google Crome.
