There's a 3rd party plugin for PyCharm which has coffee script syntax highlighting. And I think WingIDE for windows supports coffee script as well.
I'm using the former. It's usable, but lacks somethings like fixing indentation errors automatically, and auto-completion. Also the default colors under twilight theme are unreadable, so you have to modify those yourself.
