as we do not have the Gpl- Licence in Europe (mean we have it but it is intended different) i still do not know what licence to provide with the source... In Europe everything that is published has a copyright.
I don't really get the difference between GPL in Europe and GPL in the US. It doesn't work exactly the same way in court because we have different laws, but there is no "different intention" and we do have the GPL licence in Europe of course (validated already in several cases in Europe).
The fact that we have a copyright system that do not need any kind of registration does not change the fact that the GPL is a contract.
If he's doing a derivative work of a GUI licensed under GPLv2, there isn't much chance that he'll be able to licence his program with anything else than GPLv2 anyway.
