Crear un JButton redondeado y personalizado

Hola amigos en esta oportunidad voy a crear un Boton muy perzonalizado y con algunos efectos

import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.GradientPaint;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Paint;
import java.awt.RenderingHints;
import java.awt.geom.RoundRectangle2D;
import javax.swing.ButtonModel;
import javax.swing.JButton;

public class Button extends JButton{
private Color color1 = new Color(0×666f7f);
private Color color2 = new Color(0×262d3d);
private Color color3 = new Color(0×262d3d);

public Button() {
setOpaque(false);
setContentAreaFilled(false);
setForeground(Color.WHITE);
setFocusPainted(false);
setBorderPainted(false);
}
protected void paintComponent(Graphics g) {
Color c1,c2,c3;
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
ButtonModel m = getModel();
Paint oldPaint = g2.getPaint();
if (m.isArmed()){
c2=color1.darker();
c1=color2.darker();
c3=color3;
}else{
c1=color1.darker();
c2=color2.darker();
c3=color3.brighter();
}
if (!m.isEnabled()){
c2=color1.brighter();
c1=color2.brighter();
c3=color3.darker();
}
RoundRectangle2D.Float r2d = new RoundRectangle2D.Float(
0,0,getWidth(),getHeight()-1,20,20);
g2.clip(r2d);
g2.setPaint(new GradientPaint(0.0f, 0.0f, c1,
0.0f, getHeight(), c2));
g2.fillRect(0,0,getWidth(),getHeight());
g2.setStroke(new BasicStroke(4f));
g2.setPaint(new GradientPaint(0.0f, 0.0f, c3,
0.0f, getHeight(), c3));
g2.drawRoundRect(0, 0, getWidth()-2 , getHeight() -2, 18, 18);
g2.setPaint(oldPaint);
super.paintComponent(g);
}
public Color getColor1() {
return color1;
}
public void setColor1(Color color1) {
this.color1 = color1;
}
public Color getColor2() {
return color2;
}
public void setColor2(Color color2) {
this.color2 = color2;
}
public Color getColor3() {
return color3;
}
public void setColor3(Color color3) {
this.color3 = color3;
}
}y el resultado es
