This is about the same I tried to do. The cast GTK_MENU_SHELL(cmds_menu)
gave a runtime problem, because the type of cmds_menu wasn't MENUSHELL.
if I recall rightly. If you look it up inside the .xml, you'll see that
the menu structure is somewhat separate from the rest.

It's a bit longish:

I have a couple of toolbars which work fine, but I believe I can't define
new ones. Tried, and gave up. A buttonbar did the same for me. Teh
advantages of 3.5.7 (which I compiled myself) are enough to take a few
other problems along.
