If i understood that atrocious grammer, then all you need to do is put the iframe in the popup window. Put a Jscript on the index page link that produces the popup, and tell it to find your page.
Inside the page it finds, put the Iframe HTML code there and it will call to the external page and add it to iframe.
Im curious as to why you want a popup window and an iframe inside that popup window?
Wouldnt it be easier for you (if your considering editability) to use an include file inside the popup page? Saves you the iframe sizing issues and excess slider bar problems.
Again, i may be entirely off base in my response due to the grammar of the question, ive read it 6 or 7 times and im afraid i can find 6 or 7 different answers to your question, all different. LOL.
