Grandparent here. Yeah I know how to program, but the point here was to make my players a simple interactive GUI that saves its data somewhere we can all access together (e.g. the cloud). Doing that in R would be well beyond my skillset, even as an R user. Doing it with a web stack would be more appropriate, but even then it would have been a lot more work and I can't think how I'd do it without spinning up a server and setting up some http endpoints.
I mean, I work with laymen that use Excel to encode multimedia content state machines and its not pretty (dreadful bespoke schema with all the caveats you can imagine) but it satisfies their need
