@alcinnz Have you ever looked at the VisualAge Smalltalk system by IBM? I think that was a pretty interesting approach at the time. It was very centered around UI design, and attaching actions to the various UI elements.

They tried applying the same approach to other languages later, like Rexx and C++, but especially the last one did not work as well conceptually.

There's GUI design tools today that look somewhat similar to this, but don't really get to the same level and elegance that the original VisualAge Smalltalk system did. At least from how I remember it. It's been a few years...
