I am sorry, but this is not supported at the moment. We used to support 
iterators on natures, but we dropped it, because caused more harm then 
good. Usually people wanted to write their own wizard for their type of 
project and didn't want to get panels specified on the natures their 
project depends on. IMO it's your case as well, you don't want to get 
whole iterator of java nature, but just the 'Specify Java Package Roots' 
panel. Specifying wizards on natures was basicall get all or nothing 
scenario and people tend to choose nothing in this case and reimplement 
the common parts again. I know this is not ideal, but I don't have 
better suggestion now.

Eh, unfortunately you can't. At least until we will have new Wizards API 
from core team. The problem here is that panels can't dynamically change 
the enabled/disabled state of buttons - the Finish button is enabled 
when the panel is instanceof WizardDescriptor.FinishPanel :-(. Anyway we 
would need to extend contract of WizardDescriptor.Iterator and allow it 
to say that it contains some mandatory panels which must be shown.
