Maybe I miss explained... it's very easy.

Example :

Your page with the menu is menu.htm
One of your framed page is stuff.htm

You just add a 2 collumn table to the stuff.htm page.
Cut and paste the content in one of the cells and add...

<!--#include virtual="menu.htm"-->

...to the second cell. The server will take the code of the page menu.htm and insert it in the cell that has the command in the stuff.htm page to make a single page out of those 2.

Any better ?
