In short it's possible but it isn't likely to happen and even if it was ported it would only give Win32 compatible APIs which might help if someone was porting a windows application but wouldn't allow windows applications to run as they are compiled for an IA32 (intel 8086 family) instruction set. In theory the CPU could be emulated (using Bochs for example) but the performance would be too awful for words. In conclusion, theoretically possible but even if it were to happen it wouldn't do what I expect you want it to do.
