I presume you have a callback function connected to the button press 
event.  Just create code to intercept the keyboard event and go to a 
callback function that sees what key was pressed and then calls the same 
function that would have been called had the button been pressed.

The first example I found from Google was
http://stackoverflow.com/questions/10134956/in-simple-gtk-key-press-event-example-gdk-shift-mask-seems-to-be-ignored

You can see the code you need to intercept the keyboard event.

I do exactly this sort of thing in programs with the user being able to 
hit a select keyboard key or click the button (although I am using gtkmm3).
