here's your code, with the actionListener added.
You mentioned something about a JDialog, I can't work out what you're trying
to do with that.

run the code, type something into the textArea, select a 'size' from the
comboBox, and the text will change size (unless you initially select '12'
which is the default size)

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class FontSize extends JFrame
{
  private String[] size;
  private JComboBox box;
  private JTextArea area;
  public FontSize()
  {
    Container c=getContentPane();
    size=new String[]{"8","10","12","14","16","17","18","20","26"};
    area=new JTextArea(300,300);
    JPanel p = new JPanel();
    p.add(box=new JComboBox(size));
    c.add(new JScrollPane(area),BorderLayout.CENTER);
    c.add(p,BorderLayout.SOUTH);
    setSize(350,350);
    setLocation(400,300);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setVisible(true);
    box.addActionListener(new ActionListener(){
      public void actionPerformed(ActionEvent ae){
        area.setFont(area.getFont().deriveFont(Float.parseFloat(""+box.getSelectedItem())));}});
  }
  public static void main(String[] arg){new FontSize();}
}
