Originally I wanted to write it in Cappuccino and I actually started learning Cappuccino for that purpose. However, I had used JavascriptMVC for a previous project and in the interest of speed I decided to go with that. Also, I was developing our API at the same time I was writing the Part Browser and I felt more comfortable in JavaScript than Objective-J. I think Cappuccino is great though... It seems like Atlas is a killer feature and I think it will be a must-have for UIs that are more sophisticated than the Part Browser. Every time I had to build a UI element from scratch I wished I had access to Cappuccino widgets. Incidentally, I highly recommend JavaScriptMVC. It's an incredibly powerful micro-framework that is excellent for small projects but also scales extremely well to large projects. I basically hated javascript until I started using JavascriptMVC now I think programming in javascript is actually pretty fun.
