Create a custom plugin for Premiere on windows?

I've found that you can create you own custom plugins for Premiere on Mac.

Is it possible somehow on Windows? I have a bold idea for one,but without knowledge of C++

seems like it's not really possible to implement

Here is the Mac FxFactory example (How cool is that!):
