Am I supposed to use PyQT4 for programming cross-platform software in Python?

Question

So a user suggested getting PyQT.

A quick Google gave me this: Link

Is this GUI Library for pay?

If my development environment is Ubuntu Linux, what should I download on that site. I have no idea.

Please provide links if the site I provided is not correct to what I need. Thank you.

You may want to look at PySide which is sponsored by Nokia, who own QT. It's also LGPL, which is a bit better of a license than the PyQT bindings. It's also a bit more pythonic in how it works. Unfortunately, it's new, so there isn't as much documentation. On their download page you can find information about a PPA for Ubuntu which will make it so your bindings automatically stay up to date.

If you want to run PyQT then just use APT and install python-qt3 or python-qt4.
