If you close the shell you loose the environmental variables.
OSGeo4W.bat sets env vars for the current shell, they're not kept as system
env vars.

You need those environmantal variables to leaverage the osgeo4w libraries.
You ha mainly three choices:

 - run your python script inside a shell where you have setup the env
variables (like it is done by Osgeo4W.bat)
 - hard code the environmental variables inside your python script and add
them to os.environ, and set the path to the python modules with sys.path
 - make the various environmantal variables statically availables as system
env vars (Control Panel -> Systems -> etc.)
