Python, Raspberry Pi Tutor

I have a Python program that currently runs on my PC; it was written using PyCharm and utilizes both tkinter and MySQL. I would like guidance on how to install this program on other computers, specifically two different types of systems: a standard Windows PC and a Raspberry Pi. Currently, I have a Raspberry Pi set up on my personal computer, ready to be accessed remotely using VNC.

I am seeking assistance in transferring and installing this program, along with its supporting files, step by step on another PC and a Raspberry Pi. This way, I can replicate the process later without needing further instruction. Previously, someone attempted to help me through an online meeting, but they went too fast for me to follow, and unfortunately, they provided no support afterward.

I would greatly appreciate it if someone could take the time to explain each step clearly. Additionally, I would like to record the interaction for note-taking purposes. If I have any questions during the process, I kindly ask for your support.
