When I saw google saying you use either Java or straight natively-compiled C++, I guess I assumed that meant an actual C++ API. Personally I like abstraction layers for GUI: it means you don't have to deal with twenty different system-specific (and idiosyncratic) APIs. For example, I hope I never have to touch Win32 directly again.
