The CASE tools failed because they were too specialized. The basic 
premise, or idea, were that one could build a typical bussiness 
application by drag-n-drop. The tools were quite good at that. You could 
literally paint Database-relation schemas, GUIs and link them together. 
The problem were the glue, which was quite weak compared to other 
programming languages like Java or (especially) Haskell.

Because you had to do some coding in order to glue things together. Not 
much, but you had to. Also, most of the basic logic is not possible to 
do with painting, how nice that could be for a visually adept person 
like me.

I do not think the tools failed because of what you are proposing. The 
idea of presenting programs in other forms than ASCII is fine, as long 
as you do help the programmer and do not introduce unnecessary 
constraints, irritations or just general clunkiness.
