It's simpler than anything beyond using the built-in BASIC interpreter was. Which also wasn't very good. And was arguably a fairly poor platform to learn programming on--although myself and many others did. (Though in my case on a teletype hooked up to a mini rather than a local computer.)
The built in basic interpreter, though, could do this. My kids couldn't get python installed last I asked them to try, is the point.
Now, web based setups are surely advanced in capabilities for them. But, only if you know what garden to enter. I'm a fan of scratch. The kids have gotten hilariously lost when the browser is accidentally closed.
Granted, I got lost some on the computers in the header school lab. Power cycling worked rather well to get me back to interpreter.
