I think I answered the same, some weeks ago, to another guy.
So, I've tried CASL, PocketC, and now I'm testing Superwaba.
Con: the 300 Kb runtime.
Pros:
It's easy. I'm serious. The learning curve is easy, since you install it.
It's (almost) java.
It's free.
And for my interests it interfaces with the Palm apps: Datebook, Notepad, etc.
It compiles to WinCE also (I don't care)
I think that the install procedure is the worse part of the matter. But
http://www.superwaba-france.com/
has a good reference/recipe to install all the tools you need.
The home for Super waba (english, although the author of Superwaba is a brazilian guy) is
www.superwaba.com.br
How I started ?
I'm an IT Director of a Credit/Debit Card Company - so I have little extra time: I must take all the free time to work on a easy, although powerful tool with pratical, good, quick results.
I think C and C++, are the all time languages to Palm or anything elase: if you have the time to learn it, to use it; I think that C and C++ are for those peaople that are seriously commited with the development as a work life or a career.
Just isn't for me. I just don't have that time to it.
So, I'm addicted to Superwaba, because the Java/object concepts are very interesting; it's a langauge that you can use in every system (even in a chip card), and the results on a Palm are very, very interesting.
So, how I started ?
I bought 2 or 3 books about java:
1 in portuguese about Java and the object oriented programs to understand all of this concepts.
2 about the java itself :
"Thinking in java" , Bruce Eckel, PH PTR
"Java, How to Program", Deitel & Deitel, Prentice Hall
I also bought the 3 tutorial series of the superwaba on their site. I'm now following the user Interface Tutorial, wich is very, pratical and allow to use the language on the fly, in 5 minutes.
I'm trying a little program to make a Database of restaurants (in Portugal, we have a lot of places where we can eat - and drink, very well)
My next project is to interface with the Datebook, to achieve my own week view.
My dream is to make a Civ type game...
