You have to be warned that MinGW is not officially supported
(http://trac.osgeo.org/gdal/wiki/SupportedCompilers),
so not tested well especially features like Python support.
Yes, people use MinGW with success, so you may try to find
helpful information in the gdal-dev and fwtools list archives,
on the Wiki (http://trac.osgeo.org/gdal/wiki/BuildingWithMinGW)
but personally I won't be very helpful about MinGW :-(

It likely means that Python files can not be found by ./configure.
The ./configure tests if Python and its development files like
header/library are available.

Also, according to the GDAL FAQ, there are some complications possible
if used with MinGW, and as you see Python disable is suggested when
building with MinGW:

Have you tried official binaries:

Python can not be detected (see above).

That's OK.
You should know that there are two versions of Python support:
- old, called Traditional Python
- new based on SWIG, called Next Generation

The old bindings use old Numeric.
The new SWIG-based use NumPy.
So, the package you have provides old Traditional Py support that
uses Numeric.
