sounds like you want the same layout as your fathers, but added, a right side menu ... as everyone mentioned, and i have the same answer as everyone, use frame sets ...
don't know if this helps but this is how i do e'm
1.) create a new page in dreamweaver, and in the toolbar, the default set of tools being 'common', just click on the drop down and select the 'frames' toolset
2.) select the frames you want layed out in the page, in your case i'd select the top. the left, and right
3.) after selecting the frames for the page, save it as a frameset
using the 'file>save frameset as' (ie. index.html)
( this page will hold information on how your frames are set
4.) next ... you need to save the rest of the frames (html pages) that you've created ... 'file>save all'... in doing so, dreamweaver will save them all in order, with borders appearing to the current frame (html page) being saved ...
from there you can edit the separate pages on their own, or edit them all at once, if you open the frameset page.
still not entirely sure if this was helpful but, it seems you just want the same layout as you're fathers site, just with an added right menu (frame)cheers
i use webmonkey alot, and a few others through 'google'
http://hotwired.lycos.com/webmonkey/...site_building/
as well as the documentaion that comes with dreamweaver
excuse this if it wasn't useful for you
