If it's just to align text in the centre or to the right of a box, you could use a button and, by using theming, hide the fact that it's a button. https://github.com/hoffstadt/DearPyGui/issues/1111

Personally, i like PyQt or PySide they have basically everything you need to make a proper app or even simple apps, but there is another DearPyGui this is basically python version of imgui the c++ library, it provides some good customization options and can be used for simple or complex projects too, their discord is also very helpful.

There are some examples in the showcase as well. https://github.com/hoffstadt/DearPyGui/wiki/Dear-PyGui-Showcase

I was using PyQt5/PySide which will give you a nice native look but I eventually shifted over to DearPyGui for most of my smaller utilities. Its just faster for me. You will get more options and freedom with PyQt/PySide though and can use QT Designer to design your interfaces pretty easily.

With regard to structuring the files, I watched a few videos on Model-View-Controller and similar approaches for inspiration. I tried to separate the model, view and controller logic for the GUI and audio functionality, although that may not be 100% possible. It is partly dependent on the libraries that you are using, so your approach may vary. You could check out some of the apps in the Dear PyGui showcase gallery to learn how they structured their files. https://github.com/hoffstadt/DearPyGui/wiki/Dear-PyGui-Showcase

Dear PyGui is a great GUI for creating interactive charts. You can check out various examples on the showcase gallery.

It all depends on your requirements, e.g. license, documentation, appearance, performance, etc. You could also check out other GUI frameworks, such as Dear PyGui.
