I've used this code as a hack to get the column header button before:

   temp = gtk.Label('Temp')
   button = temp.get_parent().get_parent().get_parent()

Now what you have in 'button' is the gtk.Button widget that is used to 
render the column header.  Your button-press-event connection will work 
on that widget, provided you make headers clickable on the treeview:
