Create a basic UI with PyQt6

[sh4nH]

• Created a basic UI for the application with PyQt6, that parses the question files in the original application, displays gif, checks for answer.
• Added a toggle contrast button that switches contrast to dark (by updating style sheet of the Qt application).
  Here are a few screenshots from the Qt6 application:
  
  
  

Through this exercise, I was able to understand basic libraries in PyQt6, and how to create a simple UI with simple logic translation from the original application. I am currently trying out the multimedia modules of Qt and am trying to abstract out the speech synthesis functionality using espeak NG library for this purpose, since it has cross platform capabilities for windows, linux and macOS.
