kano os develop tool

I want to study kano os in more detail.
I also used raspbian. I have a question. What programs were created with the kano os gui program and kano os? java? linux? What linux did you use?

I want to make my OS as a personal project.

I want to get information from lines that do not infringe on copyright.

Hey shine999,

You can see the code for a lot of it yourself here https://github.com/KanoComputing/

Technologies used: QT5, GTK for linux only apps, HTML + Javascript for apps that work cross platform.
