so you want a DLL that is used by an other programm but is itself written 
in python?

haven't heard of such a tool. py2exe generates standalone python apps, but 
thats not what you want. wrapping DLLs so that the functions are available 
in python can be done with SWIG, thats the wrong way in this case.

if you want to expose some (python coded) functions as a DLL, i think you 
have to write such a lib yourself. this DLL would then simply call an 
embedded python interpreter to achieve the function.

the DLL init function starts the python interpreter and imports your 
script. all calls to the dll are then maped to a coresponding function in 
the python script.

embedding python in C is failrly simple as all what you need to convert 
python data to c back and forth is provided by the Python DLL. for a 
documentation of this interface, have a look at "Extending & Embedding" in 
the Python docs that have come along with your Python distribution.
the source version of python has also some example code on embedding the 
interpreter.
