If you do not intend to use NetBeans, then you can safely skip this NetBeans-specific part and go to the Vaadin and other IDEs section.
Like in Eclipse, there is a plugin available for NetBeans. This plugin is not provided by the Vaadin team, but personally by Geertjan Wielenga and Sami Ekblad (the latter from the Vaadin team). As such, we don't get to choose the version of Vaadin we want to use like in Eclipse, but it is set at 6.1.3. We will need to tweak this behavior a bit, as this is not the one we want.
At the time of this writing, the latest NetBeans version is 7.0. There are a few different distributions available. You can download them from the following URL:
