Take a look at the GObject API reference:

 http://developer.gnome.org/doc/API/2.0/gobject/

While most GtkWidgets are still derived from GtkObject, the base of
the object and type system is not part of GTK+ anymore, but has been
factored out into its own library.

The equivalent of gtk_type_unique() should be g_type_register_static().
