It should be possible, I believe OSGeo4w installs it's own python and
hence all python libraries would be on it's path not on your system
installed python.

To use the libraries with your regular python install you probably need
to and to the PYTHONPATH environment variable of your system the path to
  something like C:\OSGEO4W\QGIS\

Then import qgis.core and such should work.

ThanKs Alex, the problem is I have not been able to find any example that is free standing, all seem to be plugins or use QT to generate a UI. Can you point me to a working example, however simple (e.g. read shapefile, project,write shapefile) that can set me off on the right path?
Many thanks
G.
