Is it possible to make a non-game application with UE5?

I’m thinking about trying to make a non-game drag and drop based application using UE5’s UI tools and blueprint, is it possible to make something like this using Unreal Engine without ending up with huge build sizes or high CPU usage?

Has anyone else tried making something like this with UE before?

You can definitely do this sort of thing.

I don’t know if it’s still there, but there’s a top down puzzle project template in the launcher.
