Membuat form di java itu gampang-gampang susah, soalnya gak bisa drag n drop seperti pada VB, jadi harus ngoding secara manual. 

pertama-tama tambahkan librarynya bisa pake java.awt atau javax.swing, nah permasalahnya adalah harus mulai dari mana?? membuatnya??

gambar disamping contoh penggunaan java.awt dengan ditambah gambar.

package form;

import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.event.*;
    
public class Form extends Frame implements WindowListener{
       
        String nm = "pic/bis.jpg";
        Image gbr = 
        Toolkit.getDefaultToolkit().getImage(nm);        
  
    @Override
    public void paint(Graphics g){
        setTitle("Form Gambar"); 
        addWindowListener(this);
        g.drawImage(gbr, 1, 50, 400, 240, this);
        g.drawString("Gambar 1. 400 x 240 px", 130,251);
        g.drawImage(gbr, 500, 60, 200, 120, this);
        g.drawString("Gambar 2. 200 x 120 px", 530,190);
        g.drawImage(gbr, 300, 300, 300, 140, this);
        g.drawString("Gambar 3. 300 x 140 px", 380,440);
    }
    
    public static void main (String [] args){
        Frame f = new Form();
        f.setSize(800, 500);
        f.setVisible(true);
    }
    
    @Override
    public void windowOpened(WindowEvent e){}  
    @Override
    public void windowClosing(WindowEvent e){System.exit(0);}
    @Override
    public void windowClosed(WindowEvent e){}
    @Override
    public void windowIconified(WindowEvent e){}
    @Override
    public void windowDeiconified(WindowEvent e){}
    @Override
    public void windowActivated(WindowEvent e){}
    @Override
    public void windowDeactivated(WindowEvent e) {}
}
