Design Function in Java

So recently I created a currency converter in Java. The GUI was completely done using the design function. I closed the design function and I am wondering if there's anyway to edit the GUI after this, because the code that the design function outputs is definitely odd. Here's the GUI code.

public HorizontalView() {

initComponents();















}















@SuppressWarnings("unchecked")















private void initComponents() {

PBactionListener ButtonListener = new PBactionListener();















jTextField1 = new javax.swing.JTextField();















jComboBox1 = new javax.swing.JComboBox();















jLabel1 = new javax.swing.JLabel();















jComboBox2 = new javax.swing.JComboBox();















jButton1 = new javax.swing.JButton();















jButton1.addActionListener(ButtonListener);















jTextField2 = new javax.swing.JTextField();















jTextField3 = new javax.swing.JTextField();















setDefaultCloseOperation(javax.swing.WindowConstan ts.EXIT_ON_CLOSE);















jTextField1.setFont(new java.awt.Font("Arial", 0, 18));















jTextField1.setHorizontalAlignment(javax.swing.JTe xtField.RIGHT);















jTextField1.setText("1");















jTextField1.addActionListener(new java.awt.event.ActionListener()















{















public void actionPerformed(java.awt.event.ActionEvent evt) {















jTextField1ActionPerformed(evt);















}















});















jComboBox1.setFont(new java.awt.Font("Arial", 0, 18)); // NOI18N















for (int x = 0; x<148; x++) {jComboBox1.addItem(StringArray[x]);}















jLabel1.setFont(new java.awt.Font("Arial", 1, 18)); // NOI18N















jLabel1.setText("Converts to:");

jComboBox2.setFont(new java.awt.Font("Arial", 0, 18)); // NOI18N















for (int x = 0; x<148; x++) {jComboBox2.addItem(String1Array[x]);}















jButton1.setFont(new java.awt.Font("Arial", 1, 18)); // NOI18N















jButton1.setText("Convert");

jTextField2.setEditable(false);















jTextField2.setFont(new java.awt.Font("Arial", 1, 24)); // NOI18N















jTextField2.setText("Amount...");

jTextField3.setEditable(false);















jTextField3.setFont(new java.awt.Font("Arial", 1, 24)); // NOI18N















jTextField3.setText("$$$p00nz!");

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());















getContentPane().setLayout(layout);
