Pra começar, eis meu código:

[code]
package GUI;
import java.awt.Dimension;

import javax.swing.Box;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;

public class GUI extends JFrame{

Box box, R, L;

private JScrollPane paneR, paneL;

private JTextArea linksR, linksL;

private JButton button;

private JLabel labelR, labelL;

public GUI(){
	super("Link Xtractor 2.0 by E.J.");

	box = Box.createHorizontalBox();
	R = Box.createVerticalBox();
	L = Box.createVerticalBox();
			
	labelL = new JLabel("Links entrada:");
	labelR = new JLabel("Links saida:");
	
	linksR = new JTextArea(null,5,24);
	linksL = new JTextArea(null,5,24);
	
	button = new JButton("Gerar Saida");
	button.setSize(new Dimension(50, 50));
		
	
	paneR = new JScrollPane(linksR);
	paneR.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
	paneR.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
	paneR.add(linksR);
	
	paneL = new JScrollPane(linksL);
	paneL.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
	paneL.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED);
	paneL.add(linksL);
	
	L.add(labelL);
	L.add(paneL);
	
	R.add(labelR);
	R.add(paneR);
	
	box.add(L);
	box.add(button);
	box.add(R);
	
	add(box);
			
	this.setSize(600, 400);
	this.setVisible(true);
	
	this.setDefaultCloseOperation(EXIT_ON_CLOSE);
	
}

}
