configuring menus Fedora core

[dbrett at tcn.net]

I have never like the menus in Linux.  I am unable figure out how to 
change the menus.  I have figured out how to add to some of the menus, but 
cannot find out how to change the core of the menus.

I would like to change the structure completely i.e. no system menu. 
would someone please point me to a primer on the menu structures.

I have not had any luck doing any searches.

Thanks
david
