For Scala development with an IDE, you do need to have a plugin. Looks like this is the one for NetBeans:
http://java.net/projects/nbscala Though most people seem focused on Eclipse or Intellij. Until recently, Intellij seemed to be the undisputed best for Scala, but now that Typesafe has been working on Eclipse, that has pretty much caught up (and is what I'm using). It is also worth mentioning that Emacs or Vi along with SBT is a quite satisfactory development environment for Scala. If you are building your own project in Java and want to use a Scala package, then you don't have to do anything special since Scala produces byte code and can be used like the products of any Java package.
