I'm not sure I understand why you have to send events in this instance.
If there's no real widget associated with the widget id, why not just
pass the 'events' to an ordinary function for processing?

If you don't need them for their visible appearance, perhaps you could
attach them to a base that you never bother realizing? it would be used
solely as a place to contain widgets used for this purpose.
