a sample on what you can do with paint and draw

import java.awt.*;
import java.awt.event.*;

public class asd{
public static void main(String args[]){
Pencere pen=new Pencere();
pen.setVisible(true);

}

} 

class Pencere extends Frame{
Choice c1;
Choice c2;
public Pencere(){
setTitle("Ornek");
setSize(300,300);
this.setLayout(new FlowLayout());
c1=new Choice();
c1.addItem("red");
c1.addItem("green");
c1.addItem("blue");
c2=new Choice();
c2.addItem("red");
c2.addItem("green");
c2.addItem("blue");
Button b=new Button("ciz");
b.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
repaint();//paint direct cagrilmaz repaint gerekir
}

});

add(c1);
add(c2);
add(b);

}


String []rr={"0xff0000","0x00ff00","0x0000ff"};
public void paint(Graphics g){
Color col1=Color.decode(rr[c2.getSelectedIndex()]);
g.setColor(col1);
g.fillRect(100,100,255,100);
String str="0xff0000";
Color.getColor(str,100);

int bir=0,iki=0,uc=0;
int secili=c1.getSelectedIndex();
switch(secili){
case 0:bir=255;break;
case 1:iki=255;break;
case 2:uc=255;break;
}

for (int i = 0; i<255; i++) {
g.setColor(new Color(bir,iki,uc,255-i));
g.drawLine(100+i,100,100+i,200);
}

} 
}
