Why are there so many in the first place? (Obviously they offer 
some advantage over one-another or, in theory, the best one would 
be the only one.)

Can I write a command line program and then add a GUI later? (How 
much code would that involve re-writing?)

Which libraries/toolkits are common in professional program 
development? (Or do they just write their own libraries from 
scratch?)

What do YOU use to add a GUI to your programs?

Regarding the question wheter you can add a gui later. It heavily 
depends how you write your applications. If you mix the the 
command line code with the actual business logic, you will have a 
hard time to add a gui on top.
If you separate the business logic than it will be an easy task. 
In my opinion, TDD helps to learn how to structure your 
application best.

I currently try to write my GUI in Delphi (fire monkey) while 
most coding will be in D. I haven't found here the best way, 
still investigating...

Kind regards
