Yeah I often run into the need to develop basic UIs for data analysis for people with limited programming experience. Currently I have to settle for using Jupyter notebooks with embedded ipywidgets, but it's not still not very user-friendly. And the desktop app libraries like PyQt5 are overkill for what I need, and most of the visualization libraries I use are designed for jupyter notebooks/web e.g. Bokeh.

If I could just port my jupyter notebook+widgets+plots into an Electron window and ship it to people that'd be awesome.

A couple of years ago I started to learn Python and made something like this. Desktop applications with Flask and PyQtWebkit.
