Wow this is interesting! Does that means technically we could have any OSX app compiled for windows while still retaining OSX-like appearance? Did Apple ever released this AppKit windows port for others to use? Does apple still maintaining the port for MacOS as well or did it die along with Safari for windows?

Before NeXT was acquired by Apple, they had OpenSTEP running on top of Windows. Back in the day, you could run a NeXTSTEP app on NeXT hardware, Sun hardware as well as x86: https://en.wikipedia.org/wiki/OpenStep#OPENSTEP_Enterprisee

It was originally ported for and is still used in iTunes.

iTunes uses CoreFoundation but it kinda barely uses AppKit even on macOS.

Please do no try to make osx-like appearance on Windows. It's too alien
