SuperLike... First most constructive post from last 2-3 days on bangpyper..
That's exactly is my question.
I am saying, that I have not installed any PyQT on my system and I am not
using Python atall. {to other, please assume for GOD sake}
I have purchased a book on PyQT. and now I am writing my code using text
editor and i am not using PyQT atall.
Now I just want to do any thing with my code..
GPL + public release + nonprofit
GPL + for profit
Close software + non- profit  -- freeware
Close software + for profit -- proprietary software

My user are downloading PyQT and running my .py files...

I will learn on it, till now, I am just making and running py files. no idea
about binary part exactly.

Same question with more detailed explanation.

I never said about this, Infact my first question what on Which GUI lib to
be used..
So people can share what they worked on it,,,
