How to make Windows executable from a Python script

Recently I faced a problem that I always wanted to stay away from. My brother asked me to write a simple GUI app, which isn't a big deal, but it has to be run in Windows. Holy shit. I develop all the staff in Linux and suddenly I have to prepare a Windows-compatible app. As Python is a language of my choice, I picked it also this time. I wrote an app under Linux and then I made a research on how to port it to Windows without a need to install Python on the target machine. I found cx_Freeze which seemed to be suitable. Having read a really good cx_Freeze tutorial I wrote a setup.py script which looked like this:

#!/usr/bin/env python
from cx_Freeze import setup, Executable

exe = Executable(
    script="google_check.pyw",
    base="Win32GUI",
    )

setup(
    name = "googleCheck",
    version = "0.1",
    description = "google check app",
    executables = [exe]
    )

then run

pawel@pawel-asus:/media/5841-E712/seba$ python ./setup.py build
running build
running build_exe
Traceback (most recent call last):
  File "./setup.py", line 13, in 
    executables = [exe]
  File "/usr/lib/pymodules/python2.7/cx_Freeze/dist.py", line 278, in setup
    distutils.core.setup(**attrs)
...
  File "/usr/lib/pymodules/python2.7/cx_Freeze/freezer.py", line 186, in _GetBaseFileName
    raise ConfigError("no base named %s", name)
cx_Freeze.freezer.ConfigError: no base named Win32GUI

Uhhh.. I can't freeze an app for Windows under Linux. My bad. There is no way to "cross-compile" an app on Linux without having a Python installation on Windows partition that would be visible from Linux. If you have one, you can use PyInstaller. I had no Python on my Windows so I had to install it first.. which is a pain in the ass. Here is what to do:

1. Go to Python for Windows download page, download an installation file and install it.
2. Add your Python/scripts path to the PATH variable (go to My computer/properties/Advanced/Environmental Variables/Path/Edit then paste the path with an extra semicolon as the last entry.
3. Get Easy install installer and install it.
4. Open command line and type easy_install cx_Freeze

Now you are ready to go. Change the working directory to where you placed your application and setup.py, type cxfreeze ./setupy.py and look if there are some modules missing. If it is so, install them with easy_install. It may happen, that you won't be able to get some module in this way. Well, cross your fingers, in the end they maybe unnecessary at all to run your project. Now go to a newly-created dist folder. There is your double-clickable python application. Bon apetit.
