I have given several seminars on this subject and what I see there is 2
major stumbling blocks, beyond reading books.  One problem is psychological
and the other problem is structural--but both have the same root:

1. Developers are not psychologically prepared to develop GUIs

2. Software houses that still make character based applications are not
structurally designed to support a GUI development.

As crazy as this may sound, in many cases, designer, technical specifier,
lead engineer, and software programmer never see each other.  One person
writes a Functional specification, sent down to be turned into a technical
specification, sent down to be turned into an application specification,
sent down to become a screen or series of screens, and then delivered as a
product.  Everyone is use to working alone and off a sheet of paper, and
they expect GUI's to work exactly the same.

The first message I have to give these types of teams is: life cannot
continue the way it has--and they do not like hearing that.
