GtkCellRenderer apparently doesn't offer enough signals to simulate the
full behaviour of a real button, such as roll-over highlighting, but you
can respond to a click on text or an image.

For instance, this is how I made a clickable image cell renderer:
http://svn.gnome.org/viewvc/glom/trunk/glom/utility_widgets/db_adddel/cellrenderer_buttonimage.h?revision=1156&view=markup
http://svn.gnome.org/viewvc/glom/trunk/glom/utility_widgets/db_adddel/cellrenderer_buttonimage.cc?view=markup

There's a clickable text cellrenderer there too:
http://svn.gnome.org/viewvc/glom/trunk/glom/utility_widgets/db_adddel/

Ignore the complicated stuff in "ifndef GLIBMM_VFUNCS_ENABLED".
