What to choose node-webkit or pyqt for developing a cross-platform desktop application?

Question

Python

It is necessary to write a GUI of average complexity for a desktop cross-platform (Win, Mac, Lin) application that works with the network. From the gui, some prettiness is required, for example, the theme "as in the incentive." The choice of tools has now narrowed down to two alternatives: node-webkit or pyqt. we know about the same about node.js and python, but we only worked with gui in python. In this connection, the question is - in which of the options is cross-platform development the least painless?
We noticed that two similar applications "with a theme like in steam" - popcorntime and time4popcorn use just node-webkit and qt, respectively. I wonder why the authors of the fork decided to switch to qt, which did not suit them?

Answer 1

Qt has a fairly powerful GUI library. I tried to play with it a little, I liked it very much.
From personal experience, JS is a bit easier to work with than Python.

Answer 2

Qt+QML
