A long time ago I started some bindings with SFML 1.5. I never got very far, I just did some basic window and system modules. If you want to start with some new bindings, you should use the C bindings. It's much easier to work with and doesn't involve for you to write some C/C++ code.
But I don't think it's a good idea to start make some bindings right now as the release of SFML 2.0 is just a matter of days/weeks/months.
