I don't have a direct answer to your question, however I know that work
is being done on Etk, which aims to be API-compatible with gtk+
http://enlightenment.org/etk/

I'm not saying that creating an evas backend for gtk+ wouldn't be a good
thing ( it's certainly faster than cairo ) ... just making sure you know
about Etk ...
