Folks -

I have the need for mocking up a bit of a web UI as an administrative 
interface to some domain objects living inside Squeak. What is the 
easiest[*][**] framework to use for that purpose?

I'm sure one of the options is Seaside but I'm not sure it is the only 
game in town, neither am I sure if it's the right thing for the task at 
hand. Since I remember that various people had used a number of 
frameworks I'm curious about alternatives and tradeoffs. Any opinions or 
recommendations?

[*] easiest = least painful install, reasonably quickly to learn, fast 
intermediate results, open to future extensions (in case that UI needs 
to become "not-so-mockup" anymore ;-)

[**] One strict requirement though: It must work under 3.8/Croquet.

Thanks,
   - Andreas
