I love PyQt, I wrote lots of graphical user interfaces for my lab equipment during my PhD, was super easy to wire stuff up and replace Labview with Python. The design was similar to this app, simple frontend that allowed you to e.g. set microwave frequencies, toggle outputs or make measurements. My colleagues were initially quite skeptical but 10 years later they're still using the software and it spread to other labs, they even hired a full-time developer to work on it.
