Release Plan: qtbridge_release_plan_python_timeline

Since the release of Qt, many people have been working in exposing the framework to other languages through Language Bindings. However, having a 1:1 binding to a new language might not be the best solution in all use cases, because it implies that a lot of Qt knowledge is necessary to build the app, which could be a step learning curve for people that's not familiarized with C++.

Why Python?

Qt already has an official set of bindings for Python, through the PySide module (part of the Qt for Python project), which is a great way of writing Qt applications in Python. However the amount of code necessary to create simple applications is too much compared to other native frameworks.

How to achieve this?

Relying on more idiomatic elements to simplify the process of having a Python backend to a Qt Quick application.
