Custom Code Generator?

I have been working on a piece of code, which allows custom states to be saved in a config file and reloaded on startup (for a game engine), but as all the code has to be hardcoded, I am unable to change it easily, this is an issue if I ever want to be able to sell this as people will want something that they don’t have to spend an hour going through code to get working for them.

I had the idea that this would be doable with WordPress, but I wasn’t able to find a plugin or anything.

I need the ability to state how many variables I need, the name, type (string, int etc) of that variable and whether its public or not (boolean tick box), and then use that information to build around the code.

I have little to no experience writing WordPress plugins so I have no idea how to do this myself within WordPress.

Does anyone know how to do this or know of any plugin that would allow me to create a page with a UI for this purpose?
