Greg,

Smalltalk and the Squeak implementation in particular are good first 
programming languages. However, Smalltalk tends to be very 
specialized and it is hard to produce an application that you can 
give to other people to install. If you just want to learn and have 
something you can play with, then Squeak isn't a bad choice. As Dan 
stated, though, it is hard to produce applications that you can then 
deploy elsewhere.

The main problem, in my view, is that Smalltalk environments are 
pretty much unlike anything else you will encounter on your computer. 
Yes, you can learn programming concepts. But, you will then likely 
end up learning another language afterward to produce usable 
software. Unfortunate, but that is the current state of the art. As 
Smalltalk has been around for a long time, that is unlikely to change 
anytime in the near future.

Programming itself is actually pretty easy. You just have to take 
small steps. Understand that you won't sit down and in one night 
understand how to do everything. If you work through tutorials in 
your chosen environment, you will learn basic concepts in pretty much 
any language you choose. After awhile, you will be able to combine 
those concepts to create very involved applications. Programming is 
only hard if you look at it as a whole. The pieces are generally 
easy. The terminology, which you rightly complained about, comes 
along with that learning.
