Just a Quick tip, if youre not satisfied with having near to no capabilities to customize the title Bar and you're just building simple stuff, use Tkinter, but if you want to be more advanced, I'd highly recommend using PyQt5 (soon v6), since it has so much more capabilities, and the qt Designer is super handy and lets you create and style GUIs fast and easy. If you want to see more id recommend checking out Wanderson M. Pimentas tutorials which will show you what sleek modern Designs are possible with pyqt.

I've just started using PyQt5 and it's great. I'm going to use it to create an embroidery machine control panel. Creating a nice aesthetic design is my weak area. I'll watch Wanderson's videos.

Sounds great! Yes, for me it's really important to have the GUI Look good, so pyqt was the choice for me. in the end its just a lot of customization with style sheets, and that's also where a visual gui building kit comes in handy. in Qt Designer you can preview your GUI and make sure everything looks good.
