If it is true that most companies (mine doesn't) relegate GUI tasks to
novices, I think it's a mistake to do so. Contrary to what many think,
creating a good GUI is often one of the more complicated parts of a program
- and the part of the program with which your customer will interact most.

Current GUI programming tools facilitate easy creation of toy GUIs while at
the same time hindering the creation of commercial grade applications and
also hindering the use of more powerful code reuse mechanisms.

will remain solely in domain of highly experienced programmers.

A well designed library can facilitate the use of powerful template
mechanisms without requiring the programmer to understand how they work.
You can use Spirit, for instance, without understanding the intricate world
of expression templates.

I'd agree with that. I'd say over half of the "C++ programmers" I interview
can't tell me what the STL is!
