This sounds like advertising talk. I don't think there is well defined
meaning for such words as "average programmer", "real world",
"academic", "state-of-the-art", "best", etc. I prefer talking about
actual ideas. I try to do that when I write.

Well, many, including me, have written quite a bit on that. A lot has
been talked at this list about the pink plane vs. blue plane tension,
etc. You can start at

Then pay more attention. Squeak already includes a lot of morphs that
would be really hard to write in other language / environments.
EnvelopeEditorMorph is one of my favorites.

Well, I helped write an application that way in 1997 using VisualAge
Smalltalk (now VA Smalltalk). Also VisualWorks and Visual Smalltalk
supported or still support that way of programming. In my experience,
and that of many others, code is much better at tackling real complex
applications and at building a mainteinable system. I believe the whole
"visual programming" idea failed for professional developers.

As I said, use WindowBuilder. I've been using it for about ten years
now, in Visual Smalltalk. Take a look at www.caesarsystems.com (my
employer). PetroVR is a pretty sophisticated and good looking software.
I think WindowBuilder is pretty good. Anyway, I don't think Squeak
really needs something like that, because GUI builders only help on the
easiest part of a GUI. The real complexity is in the dynamic behavior of
the GUI, and on GUI elements that are not "widgets on a form". I write
most of the PetroVR code for non widget-based GUIs. For these things,
Smalltalk code is the best, and Morphic is much better than other
frameworks I know.

Well, I gave some pointers. Most of the stuff at
http://www.jvuletich.org/ could be useful. Also read squeak.org, the
wikis, use google, etc. Besides, study the system. It's all there.

I don't think why would you think that. I really believe you need more
reading and studying Squeak.
