If you know html and javascript you can try using rollovers. They're generally used with images, but I tried them on tables and they worked. You can set the "hidden" attribute of some tables and change them when someone clicks the links so that the page changes.
Maybe you can try putting between the <DIV> tags some different layouts of the pages you want and use them as rollovers.

Sorry if I'm not specific, but I haven't been using html at a proper level for too long.
