[Newbies] Squeak in commercial projects

[RENE PLOURDE]

Can one use Squeak to build and sell applications? My wife is a  
musician and has some ideas for a Music Theory Application and asked  
if I could build it. The choices seem to be between Squeak and  
VisualWorks.

If one built an application with Squeak are there tools for packaging  
it so that you only ship executables and not the entire development  
environment?

Thanks for any information you can provide.
