Its a little unclear what you are asking. If you do not want the original widget to process the event then you would need to redifine the keyPressEvent() to emit a signal with the event as an argument.
Then you connect your button widget to that event.  Line Edits will already send the event, and I"m not sure if you can sent a QEvent as a signal.  I don't know what it's appropriate c signature is offhand.

def keyPressEvent(self,event):
    if event.key()==QtCore.Qt.Key_Return:
        self.emit(QtCore.SIGNAL("returnPressed( QEvent )"),event)
    else:
        event.accept()
