Qt Designer

So far we have been creating apps using Python code. This works well in many cases, but it can get a bit cumbersome to define all widgets programmatically. The good news is that Qt comes with a graphical editor — Qt Designer — which contains a drag-and-drop UI editor. Using Qt Designer you can define your UIs visually and then simply hook up the application logic later.
