There are multiple ports of WebKit (the browser engine of Safari) on Windows [1], but two of them are still more or less maintained:
* AppleWin, Apple's port of WebKit for use in iTunes for Windows. I'm pretty sure it depends on DLLs that reimplements Cocoa APIs on Windows, those DLLs are shipped with iTunes. (edit: one can download the support libraries here [2])
* WinCairo, maintained by Sony and uses Cairo for rendering. Maybe someone can fill me in why is this a thing, since Sony only uses WebKit on the PlayStations.
