First you need to write:

gtk_widget_add_events(widget, GDK_KEY_PRESS_MASK|GDK_KEY_RELEASE_MASK);

To make it possible to receive such events (may work without, never tested
without). 

Then:

GTK_WIDGET_SET_FLAGS(widget, GTK_CAN_FOCUS);

Then, pressing <TAB> will eventually give you widget a focus so
it can receive button events.

If you want initially have focus on your widget, add:

gtk_widget_grab_focus(widget);
