Best way to share UI code between Pythonista and Windows platforms

[upwart]

I am working on an animation/visualisation of a discrete event simulation program. I would like to run the program both on Windows (CPython or PyPy) and Pythonista.
I know there's Tkinter on Windows platforms, but that's not supported in Pythonista as far ad I know.
And there's UI (or Scene) on Pythonista but not Windows.

Is there any package that's available on both platforms? If not, what would be the best approach to share most of the code?

As far as I know, there is not a common graphics module between Pythonista and Windows. However, Tkinter is somewhat similar to the ui module, so try to translate the code. I hope this helps.
