An applet with 3 combo boxes.

I don't think NetBeans Form Editor is going to help much, since this isn't really a layout issue, but an issue with the actual data behind the form. I'm also not sure how you're storing and accessing the data for this... it could be in a database, XML file, EJBs, etc. You also don't specify if you are using AWT or Swing for this, Swing would be easier, since it uses MVC and seperates the data a component holds from the visual representation of the component, but since you are using an Applet I'll assume AWT. Here's a quick example... it's not perfect in lots of ways... the data is hardcoded and stored in an internal hashtable for one, the user actually has to select a combobox before it's "child" combo is filled out, etc. but it should give you some idea of what to do:
