to build GDAL with MingW something like the following should work

./configure --prefix=$PATH_TO_MINGW_ROOT --host=mingw32 \
	--without-libtool --without-python $YOUR_CONFIG_OPTIONS

Then after GDAL is built change your GDALMake.opt file to 
reflect your python installation in my case

PYTHON_INCLUDES = -Ic:/Python22/include
PYTHON_LIBS =  -Lc:/Python22/libs/ -lpython22
PYTHON_CFLAGS =  
PYTHON = yes

below find a heavily hacked version of the setup.py
from the TOP GDAL directory that I just built gdal pymod with 
with my MingW system

Note you will have to change the line in the script below

LIBRARY_DIRS = ["./", "d:/usr/mingw/lib"]

to reflect your local system

You need to build and install the MingW Python Link Library 
http://www.mingw.org/MinGWiki/index.php/Python%20extensions

Once you have done this and have built the rest of GDAL

then using the script below thusly

>python setup.py build --force --compiler=mingw32
>python setup.py install --force

should allow you to do

>python
Python 2.2.3 (#42, Jun  4 2003, 10:33:42) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import gdal,gdalnumeric
>>> dir()
['__builtins__', '__doc__', '__name__', 'gdal', 'gdalnumeric']
>>> dir(gdal)
['AllRegister', 'Band', 'CE_Debug', 'CE_Failure', 'CE_Fatal', ........
............
>>> dir(gdalnumeric)
['ArrayType', 'BandReadAsArray', 'BandWriteArray', 'CE_Debug' .......

Note This is unsupported
But It works for me and should work for you if you follow the instructions

I will probably not answer any questions so if you have problems 
please ask then on the appropriate list
i.e Python-Discuss or MingW-Users

Good luck

Norman
