I am beginner in programming and need to build a sheet music mobile APP for learning Piano for my Thesis. The app can display sheet music and has a virtual piano below it (takes input from connected Piano to the computer, when a wrong note is pressed, the key pressed will be red, and when the correct note is pressed, the key pressed will be green. My question is, what do I need to build this? I am using Visual Studio, I am clueless as to what language to use, what development platform to use, what tech stack to use, what frameworks to use, and everything else. I tried googling, youtube, but to no avail. I just need to develop a simple app, as I have only 2 months to build this, which I why I am asking for guidance, I hope someone can point me in the right direction!

I tried developing it in .net MAIU but struggled to find resources and similar solutions
