Galera , estou com o pdf do php-gtk do author pablo dall'oglio. quem quiser o pdf do livro entre em contato no meu email: relaie22@gmail.com

Bom dia pessoal, estou com um problema, estou precisando criar uma gui em python para dar suporte para uma aplicação maior, mais profissional, usando OpenGL, alguém ai conhece alguma biblioteca que eu posso utilizar para fazer essa interface com exibição em OpenGL? Iria precisar fazer os botões e objetos da interface e um espaço para exibição 3D. Eu já tenho experiencia com freeglut em C, porém o glui é muito simples para essa aplicação. Obrigado.
