I'd like to build a email client prototype for OS X. For personal reasons, I'd like to use something else than Objective-C and XCode to build it (I wouldn't mind using XCode only to compile the code).
If you wonder what are the reasons, let's say that I built several iOS apps and one OS X app using XCode and Objective-C and I always disliked both the IDE and the language. I like more Java-like/C#-like languages to build software apps.
I heard of some wrapper like a Ruby one but I'd like advice from someone who built an app that way and if this is a viable way of working.
