Depending on how you read GPLv3, it may mean all libraries and plug- 
ins would need to be GPLv3 too.


There is also the BSD license and MIT license if you are looking for  
a more liberal license than the GPL.
I have seen projects use the Apache license, which you may want to  

The Fedora Project is very strict about the licensing of the packages  
in the Fedora distribution. There are good resources for licenses at :

Content is not code, and a license for code is generally not a good

Skins are a grey area, they are part code, part content, but I think  
a skin leans more toward content.

A Creative Commons license may be more appropriate for skins.
