I really like sqlite, lua and luajit's "C" implementations. For C++ I think Qt is pretty reasonable, also the Unreal Engine. I'm using Java at work at the moment (Google Web Toolkit mainly, and learning it on the fly), but feeling the love in there. Some things are crazy (enums :)), others looked strange at the begining (dependency injection), but I really like the interface / class split - the interface "Set" vs the implementation "HashSet" (or something else).
