I need a c++ programmer for a custom Linux gui

Make a Linux GUI like the included video in c++? [login to view URL] including a touch friendly lockscreen with controller support as well. Compiled on arm and I want it built on arch. I want a game overlay so when you click the home button it displays the game screen with the paused game in the background. It must also support touch and controller support as well as an on screen controller and touch keyboard. I also might want steam store and library integration in the future. If you need clarification feel free to ask me.
