[PyQt] distribute pyqt application to windows users

[G. Allegri]

Hello list.
I'm a newbie with PyQT, so please excuse my questions if they're trivial.
I'm writing an application on my Linux (Kubuntu) box, where installing
PyQT is as easy as any other "apt" distribution. The utility'target is
both Linux systems and Windows (XP/VIsta). Two questions:

1 - What binaries should I install to build PyQT apps directly on
Windows? Is the setup of QT libraries, SIP and PyQT enough? I ask
because I don't have Windows now, but I'm considering to install it...
2 - What is the easier way to distribute a PyQT app for Windows users?
Do they have to download the QT libraries, SIP and PyQT by themselves,
or there is a way to avoid them to do it? Does PyInstaller help?

Ok, I stop. Enough questions :)
Thanks for any help,
Giovanni
