I'll give it a try, thanks a lot!

http://www.maemo.org/platform/docs/tutorials/Maemo_tutorial.html#Menus

"Two different GTK+ ways to create menu are supported, making them manually
and using GtkUIManager. GtkUIManager is new action-based method to create
menus and toolbars from an XML description. This tutorial uses only manual
creation for both, you can read more about GtkUIManager from:
http://developer.gnome.org/doc/API/2.0/gtk/GtkUIManager.html"

Or maybe I've misread this ;-)

It's true that the svn repository holds a ui-manager supporting
