I think a wizard should handle its own business and not return any data
to be processed by some other methods. That is what I have done.
Otherwise you need, upon pushing finish or whatever, copy all your
values from your text box into local variables. Then add a method that
returns that local variable to your dialog/wizard class. I think that
is the best way.
