Clara 2E Building a standalone app for kobo

Hi everyone,

I'm looking for a way to build a standalone app that I can run on my kobo device. say for example I build a simple sudoku app with c++ qt framework and launch it on my kobo through NickelMenu.
Does anyone know such a thing is possible and if there are ressources that can help me with that?

I have a personal project I want to work on and I'm not finding well explained ressources.
