Simply bind a function to the "key_press_event" event.  You can look at
yagIRC for a specific example of this, but here is a quick example off the
top of my head.

int keyevent(GtkWidget *widget, GdkEventKey *event)
{
    if (event->keyval == 'a') do_stuff();
    return TRUE;
}

int main (int argc, char *argv[])
{
    GtkWidget *window;
    /* ... */
    gtk_signal_connect (GTK_OBJECT (window), "key_press_event",
                        GTK_SIGNAL_FUNC(keyevent), NULL);
    /* ... */
}
