If what you want is a web IDE that supports visual development, no standalone Python IDE has such support. But you can use Python in IDEs that do support these features.
1.) ActiveGrid (http://www.activegrid.com/) - closest visual web IDE where Python is a first class member. 2.) Use ASP.NET with Boo or IronPython. Not seamless IDE-wise. 3.) Wait for Coyote to finish (https://coyote.dev.java.net/). It is still J2EE but you get to use Python. Netbeans, unlike JDev does not have data bound widgets available. -- http://mail.python.org/mailman/listinfo/python-list
