I suspect the users requirements could be me just by putting the label in a 
GtkEventBox, and setting the event mask to receive a button press event.  It 
seems pointless to use a GtkButton object and then remove anything that makes 
it look different to a label: in that case a precise emulation of the timing 
of a button clicked event would be irrelevant (the button press and release 
is invisible).
