All this is possible. What is the purpose of it?
I am exploring the idea of developing a web-based service aimed at web
designers/developers which allows you to view your page design within
multiple browsers and platforms to ease cross platform design
headaches.

All that could be done from within a webstarted application*,
and it will be easier to deploy, and lower maintenance.
You could do a single-pixel applet without greatly affecting the layout of
the page. I think that would be the easiest approach.
For the developer, maybe, but not for the people wanting
to test a web-page!
Using this approach*, the applet element needs to be inserted
into each page that requires rendering.
You also need to ensure the user is not running an anti-spam
or other browser plug-in that removes 'tiny or invisible'
page elements, for that to work as expected.
And ensure that each browser (for which a page render
is required) is correctly configured to run trusted applets.
* But then, if the image needs to be 'pixel perfect', one
can only assume that a 1x1 pixel applet will throw out
the page layout by ..at least 1 pixel.
......
...you are going to run into problems with the applet.
Is it expected to be up and running in a separate browser
window to the target window?
Note that the <applet> element does not need to be
written into the web page(s) of interest, using this
approach. The trick is to ensure the web page is
on-screen and on-top.
You mentioned frames, so the other possibility is to embed
the applet in a hidden frame and the content page in a different
frame. ....
...and this is a second applet based strategy that gets
around the problems of the 'in the page' approach, but
also introduces others..
