Embed html in flash


This might be a newbie question, but I didn’t find an answer.

What I want to do:
I want to make a new homepage. On one site, I want flash to show my guestbook (which is in html). I got a fullscreen flash file with the dimensions 1000x650 and the place where the guestbook should go is about 600x425. Flash should get the url and the html file and display it in this box.
Is that possible?
