I'm building a site that is built for 800x600 viewing. It has a yellow background.

Now if someone views from a larger screen, I want both sides, whatever isn't used by the main page to be red. and maybe eventualy have an image running down the sides.

I thought of doing it with a table, but then I realized that anyone viewing 800x600 would have to scroll to the side in order to view the page.
