Hi mor,
quite simple:
1) Download and unpack the new official SDK under LINUX.
2) follow instructions to get one of the official demo apps to be build.
3) Learn the API "innkview" (header inview.h") by analyzing / modifying the demo apps.
4) write your first own app.

5) publish them here for free
I'm looking forward to your new apps!
Knowing Linux is an advantage, but not a too big one.
Knowing "C" is very necessary. But you can use "C++" as well (and it seems a good thing to use it - to my mind).
