It should also be possible to instantiate a new derived C++ class as a
wrapper for an existing GTK+ instance, instead of one of the standard gtkmm
classes from Glib::wrap(). But the GTK+ instance would have to be generated
from libglademm, because it needs libglade to instantiate a gtkmm_ Gtype.

I'm thinking of something like this, and some time ago I did the gtkmm_
stuff in libglade to make it possible:

class DerivedButton : public Gtk::Button
{
  DerivedButton(GtkButton* cobject)
  : Gtk::Button(cobject)
  {}
}

Or maybe it should have a DerivedButton::DerivedButton(Gtk::Button*) and
take ownership, but that might get complicated.
