Você precisa primeito ativar o modo "blend".

glEnable (GL_BLEND);
glBlendFunc (GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

A partir daí, utilize as funções glColor4f.

A quarta componente é o alpha, que indica a transparência.

Mas isso só funciona pra objetos da cena.

Se você quiser a janela transparente, é outra história..

Té mais,
