Python Soundboard (evilArthas)

Good evening to everybody here. I am a new student to Python, and especially a new one to GitHub, and I was hoping to see some help from here. I am working on an application which I will further transfer to Androids, nothing unusual just a soundboard with phrases from a twitch streamer. The problem is, the whole scrollbar thing is not working, and I would like to ask for help here, if it is possible. Thank you very much in advance. (Design thing is what I will be working in the end, everything is not really on their places)
