If your button is named "end_button", the function
generated in "callbacks.c" will be named
"on_end_button_clicked(/* a bunch of arguments you
probably don't need to use */)". This is about the
same as the VB Private Sub cmdEnd_Clicked() procedure
(assuming you named your button cmdEnd). You have to
put your code to end the program here. I don't know
what your program does, but this may as simple just
saying "gtk_main_quit()"
