Help with making a plugin or creating a new server on same octopi installation

What is the problem?

I want to start an apache server on the same raspberry pi as octoprint, will that cause any issues?
I have tried finding a plugin to control my LED strips but I can't seem to find one that works. Now I would love to make a plugin, but the guide I'm following makes an HTML server. If there's a way I can easily make a plugin for octoprint using the HTML thing as a backbone, I would love that. However, if not I will just run a separate server to control my LED lights.
That's the guide I was following: https://www.instructables.com/WebsiteWiFi-Controlled-LED-Strip-With-Raspberry-Pi/
And I specifically want to use pigpio, which can also work with python.

What did you already try to solve it?

I tried a bunch of plugins and tried learning how to make plugins. I need more help/time.

Have you tried running in safe mode?

Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

The work has already been done: OctoPrint-GpioRgbController

I would love to make that work, but it keeps crashing my octoprint.

If you share logs of that crash, perhaps we'll be able to help you getting it to work.
