Is there a preferred framework for custom GUI applications other than normal GUI?
I've played with wxPython, but it seems to be geared towards "standard" applications - things that have their own menu and toolbar file systems, and more.
My needs are pretty simple. I just need to be able to play some mp3 files, show some images, and be able to pack them into .exe and .dmg. Also, being able to play a small mp4 would be great.
Unfortunately, I understand that there is no definitive answer to this question and therefore does not fit the format, but it will be useful to appreciate the push in the right direction!
Pyqt / pyside / Qt has a new declarative QML that seems to have an application focused on a kiosk type interface. You can basically create something in Photoshop and use it as your user interface
Pygame is the common choice for fully customizable user interfaces.
