Building a Google Drive Direct Link Generator | PyQt5 Tutorial

In this tutorial we are going to build a Google Drive Direct Link Generator application with PyQt5 in Python.

Two main things we are in this tutorial:
1. Building the app
2. Package the app with PyInstaller so you can share the program with other people.
