button_(press|release)_event is the right choice for this. This should
only be used for things like drawingarea or other things that need low
level access - button_press_event is low level thing and using it
elsewhere might make your application act differently from other gtk
applications.

Hmm, you're using it for Gtk_Button's? what exactly are you trying to
do? Is there some reason normal buttons dont work with it? Binding a
button click of other mouse buttons atop of a button to mean different
thing is a bad thing (I wouldnt want to use app like that - it might
become new xfig with completely horrible user interface :)
(only use for that I could imagine is to assign a different menu atop of
each Gtk_Button... but... I dont know if thats a good idea either..)

Yes, if you really really want to do this, then inheriting from Gtk_Button
and overriding the button_press_event_impl() -method will do it.
