If you are talking about a field with editing tiles, then you are doing custom control. In the general case (you didn’t specify which UI you basically use): you inherit from some component, for example from Button, overload Draw, OnMouseClick and so on from it, and implement the functionality you need.
Everything else is basically done on some kind of Qt.
