I will need a file save dialog box (re-use the file-io dialog box, of course).  I will probably need another box which will ask how the user wants his/her code generated.  So far, I can only think of:

C++ vs. java
with or without the comments included (also does he/she want comment space allocated like stubgen... I could even re-create stubgen comments too)
any defaults (like public, void return types, etc.)... this mauy be handled by some preference module that hasn't been actually determined yet (Freddie and I talked about it briefly).

well, that's all I can think of so far.  There are probably more things I haven't thought of yet, amybe stuff like header file layout, function declaration layout, etc.

I will also need message boxes for errors and such.  Additionally, if I have time, I may want to ask for some user info/specification during code genreation if I am not clear on what the user means (such as some function declaration that is invalid, like is named a keyword or something).
