It's much easier to program a GUI in PySimpleGUI than PyGame.
Do you have tkinter on your platform?
You should be able to hook up your GUI to anything you want. To display your information, read the data using your code, then plot the data using a Matplotlib / Pyplot call. You can then display that graph in your GUI.
There is extensive documentation on how to use it and there are several example programs posted the demonstrate hooking it up to Matplotlib.
This is strange behavior. When I assign it a new ssid / pw, it acts as an access point, and I can directly connect to it. When I delete the device, and add it again with an ssid / pw for the local wifi, it connects to that, and subsequently connects to PyBytes.
