Pythonista UI module is a part of Pythonista, which is an integrated development environment (IDE) for Python primarily designed for iOS devices like iPhones and iPads. It provides a user-friendly interface for creating iOS apps using Python.
However, Pythonista and its UI module are specific to iOS and are not available for desktop IDEs. If there have been any developments or third-party tools that enable you to use the Pythonista UI module on a desktop IDE, I would not have information on them. You may want to check the Pythonista website or other sources for the most up-to-date information on this topic.
