If your program is running on Win32, is your goal to get at the 
Microsoft Windows messages before they are processed by GTK+?  
Then take a look at gdk_window_add_filter().

Is your goal to have all of the buttons of your application use the same 
callback function for, say, the "clicked" signal?  A single callback 
function can be connected to more than a single widget.  For example, 
you could define a function such as...

void on_any_button_clicked(GtkButton *button, gpointer data);

...which can be connected to any number of widgets that you derive from 
GtkButton.

Do you have another reason to place all of your event handling into a
single function?
