Ciao a tutti, ho creato una classe che contiene una form. Il problema è che non so come lanciare la form stessa

posto il codice così forse potete capire qualcosa di più in ciò che ho scritto.

codice:
import javax.swing.JPanel;
import javax.swing.JTextPane;
import javax.swing.JFrame;
import javax.swing.JButton;


public class postit {
	public static void main(String[] args) {
       //System.out.println("Ciao!");
       return initGUI();
    }

    public void initGUI() {
        jButton1.setText("jButton1");
        jButton1.setBounds(new java.awt.Rectangle(131, 144, 56, 23));
        jButton1.setLabel("Nuovo");
        jButton1.setActionCommand("bNuovo");
        jButton1.setFont(new java.awt.Font("Arial", java.awt.Font.PLAIN, 10));
        jButton1.setMargin(new java.awt.Insets(1,2,1,2));
        jButton1.setMaximumSize(new java.awt.Dimension(37,21));
        jButton1.setMinimumSize(new java.awt.Dimension(37,21));
        jButton1.setPreferredSize(new java.awt.Dimension(37,21));
        Frame1.setBounds(new java.awt.Rectangle(0,0,438,300));
        Frame1.setSize(new java.awt.Dimension(200,200));
        Frame1.setBackground(new java.awt.Color(255, 255, 0));
        Frame1.getContentPane().setLayout(new java.awt.GridBagLayout());
        Frame1.getContentPane().add(jPanel1,
        new java.awt.GridBagConstraints(0, 0, 1, 1, 1.0, 1.0, java.awt.GridBagConstraints.CENTER, java.awt.GridBagConstraints.BOTH,
        new java.awt.Insets(0, 0, 0, 0), 98, 177));
        jPanel1.setBackground(new java.awt.Color(255,255,0));
        jPanel1.setLayout(null);
        jPanel1.add(jButton1);
        jPanel1.add(jButton2);
        jPanel1.add(jButton3);
        jButton2.setText("jButton2");
        jButton2.setBounds(new java.awt.Rectangle(68, 145, 56, 23));
        jButton2.setActionCommand("bModifica");
        jButton2.setLabel("Modifica");
        jButton2.setMargin(new java.awt.Insets(1,2,1,2));
        jButton2.setFont(new java.awt.Font("Arial", java.awt.Font.PLAIN, 10));
        jButton3.setText("jButton3");
        jButton3.setBounds(new java.awt.Rectangle(6, 145, 57, 23));
        jButton3.setActionCommand("bLeggi");
        jButton3.setLabel("Leggi");
        jButton3.setMargin(new java.awt.Insets(1,2,1,2));
        jButton3.setFont(new java.awt.Font("Arial", java.awt.Font.PLAIN, 10));
    }

    public JFrame Frame1 = new JFrame();
    public JPanel jPanel1 = new JPanel();
    public JButton jButton1 = new JButton();
    public JButton jButton2 = new JButton();
    public JButton jButton3 = new JButton();
    }
Grazie in anticipo per l'aiuto
