This probably belongs in GUI and events/callback
thread. I must say it is a good idea to compromise
the heated event/callback discussion. I have not seen
a really cool feature of events yet.

This is a very cool idea. I do think it is a bit on
the Fudgets (experimental) side of things though. For
CGA I would probably lean against such an idea since
it hasn't be practically proven. I'm not sure how
often I would use this in my day-to-day gui coding. I
do really like the idea of "lazily" creating widgets
as it is much in the spirit of haskell ;-).

Although the GOI Attributes are extremely verbose in
comparison to the standard functional syntax, I see
them to be superior in many ways: those unfamiliar
with CGA would have a much better time picking up the
syntax, and it also shows itself to be an improvement
of the Object Oriented style of default parameters.

I personally think this is out of scope for an initial
release of CGA, but this is most definitely something
to keep in mind.
You've got some very interesting ideas, I hope you
continue to participate in this group.
