Hi ,
Ok so I followed rour advices !!!
I use now the sge wich is an extension of SDL as you all know 
and it
works pretty fine for what I expect to do.
I would like to learn more about Open/Gl but the fact that I don’t know
anything about it is a brake for me as I will have to learn it before to
use it… and I’m quite short in time !!!
So I will try with Open/Gl but later…
Bye all
