Copyright and licenses are different things. Authors always hold 
copyrights until their work becomes of the public domain. Before that, 
the copyright is of the author regardless of the license.

No, you can't incorporate GPL code without your software being infected, 
meaning you have to distribute the source of the programs that you 
develop that incorporate GPL code. This basically rules out closed 
source programs like the original poster wants to sell.
