  Perhaps I`m not the right person to answer this since I do not have 
too much experience working with Windows.I was succesfull compiling KAWA and some 
wrappers for it with gcj into a dll and then using the API from c and c++ both with 
gcc under Cygwin and with Borland compiler with C++Builder (had to make a lib from dll but this 
worked too).
 The most difficult thing was getting the headers right and seting the right export symbols 
from dll. Then in most cases I had to load dlls at run time (i.e. LoadLibrary(..)) and get 
the functions I need (i.e. GetProcAddress()).Also for Borland compiler only c functions may 
be exportded from dll`s so I had to flatten the APIs I needed into c functions.

 So it is possible !
