I had made some questions regarding php-gtk(there are only 4 php-gtk tagged questions and 3 are mine) and I end up answering myself because no one answer them.
I know is a strange language selection but I was attracted to it because it runs on several OS's and the fact that I can reuse some of my code (also the apps end up looking good and I can make little installers in NSIS that just rocks).
Is there a better alternative, that is free(as freedom) and can run on several platforms?
