I won't go into those my-one-is-bigger-than-... wars, but using GTK+, I
can easily fetch single keypresses/keyreleases. Look at this snipplet:

static gint
keyboard_event_handler(GtkWidget *widget, GdkEventKey *event, gpointer data)
{
	switch(event->type) {
		case GDK_KEY_PRESS:
			printf("Press:   0x%04x\n", event->keyval);
			break;
		case GDK_KEY_RELEASE:
			printf("Release: 0x%04x\n", event->keyval);
			break;
		default:
			/* Make compiler happy at using enums */;
			break;
	}

	return TRUE;
}

window_main  = gtk_window_new(GTK_WINDOW_TOPLEVEL);
...
gtk_signal_connect(GTK_OBJECT(window_main),
	"key_press_event",
	GTK_SIGNAL_FUNC(keyboard_event_handler),
	NULL);
gtk_signal_connect(GTK_OBJECT(pl_window_main),
	"key_release_event",
	GTK_SIGNAL_FUNC(keyboard_event_handler),
	NULL);
...
