Not necessarily -- see below.

Well, there are two sides: yes, this is what the code partially does
below. Partially not: it sends "messages" to an object and that
could be implemented in C by

void receive_message(char *msg, char *param) {
	if(!strcmp(msg,"quit")) {
	} else if(...) {
		...
	}
}

so it would be possible to switch around buttons and menus and so on
since the signals would be sent as these messages or method calls.

Or the receiving end could be a CORBA object.
