Which graphic 2d c++ engine to choose for learning?

Question

C++ / C#

I would like to find a simple OOP wrapper over SDL in the spirit of pygame or processing for c++.
1. The most simple interface.
there should be no code in a hello world program that is incomprehensible to a beginner.
2. Drawing geometric primitives, optionally sprites.
3. It is desirable to be able to work with the keyboard.
Usage should not be much more complicated than something like this:

ge::Window w(640, 480);
w.show();
while (true)
{
  w.fill(ge::white);
  w.draw_circle(50, 50, 30, ge::black);
  w.flip();
  ge.delay(30);
}

Performance and special power is not required.
