There isn't at present. You can check out the svn tree, and there are visual studio 7 and 8 project files for building the pluto stack on windows, makerelease will also produce the necessary binaries for the different orbiter releases we have now....
however as it stands, we produce windows targets for:
* Win32 desktop
* Windows CE 4.x (arm and x86)
* Windows Mobile 2003 (arm.. this is our PDA orbiter)
* Windows Smartphone 2003 (motoQ) and 2005 (Palm Treo 700wx). These are mobile orbiters, and work differently from the others above.
We need to produce targets for the current windows mobile devices, in addition to our present targets (WinMO 5.x and 6.x).
We will help as much as we can, but please understand, you're on the ground floor, a lot of research will need to be done on your part, and it's not all written down, if you get my meaning.
A lot of this stuff was simply inherited, we need to figure it all out.
