15 years ago I was at the same place you are. Believe it or not, I built an entire web-like UI using Tcl/Tk!

But then I hit limits and started re-implementing the wheel. So I bit the bullet and learned all those layers of web development. Never looked back.

When you get to that point, may I suggest you master HTML and submitting forms. You can do a lot without Javascript. Look at Laravel for an easy to comprehend framework (PHP). It is just perfect.
