Using Unreal Engine to create GUIs for applications

I don’t really know how to put this question. Say I create a room with top down view with 3 panels placed with the walls. Accessing each panel opens an application coded inside the Unreal engine, something like a minigame say… Can i do this?

Not sure what you mean, if you’re thinking about connecting UE4 to other games, why not just make those games in UE4?

im thinking of linking a compiler i made to the UE4 interface. Use to interface to access it just to give a look to the project. is it possible?
