	You must have missed the menuManager chapter of IM IV.  On Pages 55 and
56 I find the following routines for doing what you wish (I use them for keeping
my own Windows Menu in appls).

	DelMenuItem(menu:MenuHandle; item:integer);
	InsMenuItem(menu:MenuHandle; str: Str255; item:integer);

	This makes it real easy to simply add and delete the menu items which 
are associated with the windows.  You will also need a routine which parses the
menu and finds the item which matches the window title in order to delete it,
but that is pretty simple.  Another nice thing to do is to keep the window list
in alphabetical order so that the user can find things quickly with lots of 
windows open.  You should also use some sort of mark (check, diamond, etc.) to
signal which is the frontmost window.
