i don't really know why you feel this way:

  gint button_release_handler (GdkEventButton *event) 
  {
     switch (event->button) { 
     case 1:
         printf ("button 1 (probably left) was clicked\n");
	 break;
     case 2:
         printf ("button 2 (probably middle) was clicked\n");
	 break;
     case 3:
         printf ("button 3 (probably right) was clicked\n");
	 break;
     default:
         printf ("button %d was clicked\n", event->button);
	 break;
     }
     return TRUE;
   }	 

connect this to the relevant widget's "button_release" event and
continue from there. AFAIK, its no easier to connect "user-defined
actions" to right button clicks than it is to any other button clicks:
GTK+ doesn't provide any particular method for doing this. By
user-defined, I understand you to mean things that the user (not
programmer) wants a button click to do.
