I can't see any code ? How can we help without code examples of you problem ?
If you post reams of code, I doubt you'll get a response - so you'll need to post a succinct example which demonstrates your problem.

You can :-

1) Disable the LayoutManager (using a null). You can place your components exactly where you want them, and with the size you want them (using setBounds). The drawback is that nothing will resize/relocate automatically when the containing panel is resized.

2) Use a variety of nested LayoutManagers. Eg. Put labels into a one column GridLayout panel and their corresponding fields into another one column GridLayout panel. Put these, respectively into the WEST and CENTER of a BorderLayout panel, and then this latter into the NORTH of a BorderLayout panel on your TabbedPane. This can get a little intricate for large numbers of components, but for reasonable numebrs you can achieve good results.

3) Use a GridBagLayout with GridBagConstraints to control the layout of the components. The GridBagLayout is an advanced LayoutManager which takes a bit of getting used to.

4) Forget Swing/AWT and switch to delivering your content via a web browser. You'd need to use JSP / Servlet or some Web MVC framework like Struts in a servlet container such as Tomcat, and then use HTML / CSS (or even AJAX) to deliver your front-end interface.

GridBagConstraints only work with the GridBagLayout. The GridLayout is a much simpler beast and lays out the components evenly in the panel space.
