I did notice the Java wrapper, I'm fairly good with Java as well. I might give that a shot.
I wouldn't recommend it as it is very incomplete in covering the SDK APIs. Except if you have the will and knowledge to extend it, which is not super easy. It'd be useful though if your plugin has a complex UI, as you could use Swing, much cleaner and modern than old Win32 UI APIs. What kind of plugin do you want to make ?
IIRC, On the C# front there's foo_title with a C# wrapper, I think the source is available. But I don't think it's complete either in the coverage of APIs.
