Je me suis posé la même question.
Oui, si on en croit la page http://code.google.com/webtoolkit/makinggwtbetter.html dont voici un extrait: GWT took off much faster than we expected, and it quickly became clear that the most sensible way to advance GWT quickly would be to open it sooner rather than later. While we've never actually felt particularly stingy about keeping the source closed, now the all code for the GWT Java to JavaScript compiler, the hosted mode browser, and so on can progress before your eyes. We're very much looking forward to contributions of ideas, bug reports, and patches.

Finallement, j'ai été voir rapidement dans Subversion et j'ai trouvé le compilo sous licence Apache:

Je vais peut-être me remettre à développer des applis web...
