http://developer.gnome.org/doc/API/2.0/gtk/gtk-General.html says "It's OK to 
use the GLib main loop directly instead of gtk_main(), though it involves 
slightly more typing."  So with GTK+, instead of calling gtk_main() you can 
instead call g_main_loop_new(), and then call g_main_loop_run() on the 
returned GMainLoop object (and store that object for future use if required).

Presumably (although I do not know as I haven't tried it) instead of calling 
Gtk::Main::run(), it would be possible to call Glib::MainLoop::create(), and 
then call Glib::MainLoop::run() on the returned MainLoop object, which you 
could store.  You would still, however, be required to have created the 
singleton Gtk::Main object prior to doing so.
