How can I write a GIU in Squeak? I'm a Smalltalk newbie and I'm using Cincom's VisualWorks at the moment but I'd like to give Squeak a try. I see that Squeak has Morphic for graphics but for the life of me I can't seem to find a package to write an MVC based GUI.
Squeak includes all the classic MVC classes, but you can also create GUIs using Morphic, indeed much more interesting ones than you can (easily) with MVC - that is after all why Squeak was created!
Note that you may get a better response posting somewhere more specific - there don't seem to be many Smalltalk people on SO. Try http://news.gmane.org/gmane.comp.lang.smalltalk.squeak.beginners to start with.
