GTK_TYPE_... macros are really a shorthand for gtk_..._get_type() calls that register that given type. If you don't register the type, g_type_from_name() should not return it (and in fact your snippet returns to me that neither GtkButton or GtkFrame are defined). If g_type_from_name("GtkButton") is non 0, you have GTK_TYPE_BUTTON or something equivalent before it.
