title: How to add and remove components from particular coordinates in GridBagLayout?
body: <p>I am new to swing, am trying to make a form in which you can navigate to different panels by the click of buttons on the left-hand side, to fill out forms(panels) appearing on the right-hand side, and I am using the GridBagLayout for the purpose. I am trying to remove the current panel on the click of the JButton and then add the corresponding panels I created by extending JPanel to classes. For ex., if I click on the accountDetailsButton, I wish to open up the accountDetails Panel, somewhat like switching tabs. I want to replace whichever panel is open on that position with the accountDetails Panel, and since any tab may be open, I need to exchange the panel on the basis of coordinates instead of the component name. I don't know how to go about it as I want to remove and add components on the basis of coordinates on the frame, and the name of the components may not be known. Here's the code.
  Thanks a lot in advance!</p>

  <p>I wish to display the corresponding panel on the right-hand side of the frame when the corresponding button is clicked. For ex., if I click the accountDetailsButton, I want to replace the previously visible panel with the accountDetails panel (the code for accountDetails has the accountDetails class extending JPanel). This is done to get the feel of switching between tabs in a way.</p>
