Well, if you read the first post carefully you will see that amulegui did compile on windows but it doesn't work (as in "connect to amuled and let you do anything with it). Another point is that amulegui is still somewhere between late alpha and early beta stage (on linux), being incomplete and under heavy development. Right now it's only for those curious enough to compile it, try it and report the errors with it so they can be fixed while the rest of the basic functionality is being implemented.
There will be windows binaries for amulegui and amule when they are supposed to work...
