Welcome to DaniWeb!

People here will be happy to help you - but you'll get the best value from that if you ask specific questions.

Looking at your code there are a few small points of feedback that jump out...

You have a constructor that just goes on for hundreds of lines, which makes it almost unreadable and certainly unnavigable. Much better to break out sections into simple well-named methods so we can all see what's going on. Eg have a method for each of the panels, that returns a completed panel ready to be added to the JFRame.

You have text fields with maximally-unhelpful names. Much better to give them meaningful names for clarity and to avoid mistakes.

You use null layouts and pixel bounds. That's OK until someone else tries to run your program on their high-res screen, or their new iMac, when none of the text will fit and everybody will look enbarassed. Using layout managers is a bit of a learning curve, but they exist for a very good reason.
