Moving GtkTreeModel to glib?

[Diego Zuccato <diego otello alma unibo it>]

Hello all.
Is $SUBJ possible [maybe in Gtk3]?
It could be really useful to not depend on whole gtk. After all, a
Gtk[Tree|List]Store is a data type like a GList...
At least if it was in glib it could be used in libgda, w/o having to
reinvent the wheel. Then some gnome-db widgets could become really simple.

BYtE,
 Diego.
