It is done automatically in tomgtk ;)
tomgtk basically provides a proxy TOM object for everything used in Gtk.
And it stores the TOM object with set_data. So for example, if
I somewhere receive an GtkWidget* as an object the signal relaying
function will either return the correct proxy object, or create a new one

I see two problems perhaps with this TOM-only subclassing:
-) gtk code sees the wrong class. Not really pleasing to me personally.
-) Don't know if I can override signal slots that some super class has
   overriden by a C function (as in gnome-hello-7-mdi).
