I would even argue it is much better than trying to do so on a more modern system, as you directly can just use graphics and color (which is both fun and helps teach a lot of programming concepts that are useful to know for building UIs later) without wasting a ton of time learning some UI toolkit that will be neither instructive nor actually-useful in the real world (as even if you choose a good one, it is almost certainly going to be obsolete by the time you go to get a job).
