My answer to this problem is to use a linked list of structs, each of which
contains a pointer to a single window. The best thing about this
is that no one window has to be the 'base' window, and I can happily close
windows at random without the risk of closing the whole application. I've
used this principle successfully with a 'file manager' like utility (it's
actually a port of moxfm - the Motif version of xfm - to GTK+).

If I needed a parent window, which had menu items referring to each child
window, I would dynamically add a menuitem for each child window as it
is created.

Hope this helps,

Chris
