It seems I didn't express myself very clearly. I was trying to suggest to stop using the GUI builder. In this case it is necessary to remove the
*.form files from the project, otherwise you'll clash with Netbeans if you try to modify the generated code. You can leave the actual source code untouched as long as you don't need to modify them, and rewrite them only when you need to modify the layout significantly, so maybe you'd be able to spread the overhead over a time long enough not to break your existing schedule.
I don't understand exactly the problem you face with the GUI builder, and I'm afraid I wouldn't be able to help anyway, my affair with the builder was fairly short. Sorry to disappoint.
