I get what you're asking, but there's no way to do that.
iMovie Projects have the unique
.iMovieProj extention that only iMovie uses. So there's no way to just transfer your iMovie project to a PC.
However, you could export the project as a high-quality DV file, transfer it to the PC, and then burn it (assuming you have some PC software that will make a regular DVD from a .dv file).
Hope that helps (and I hope you don't need to use a PC too much

)!
