Swing GUI not loading in Java app

1

This might be a stupid question but I am so good at asking them! I am creating a Java application, needless to say it runs on tabs, and I have been using the Swing package to add my textboxes, buttons, etc. Everything looks fine and dandy in NetBeans but once I compile/build/run the app it shows up as a native Java window and buttons, textboxes, respectfully. Am I missing something that would allow what I see in the IDE to be opened when the .jar is run, in terms of the GUI?
