you can start from something like this:

Code:

import java.awt.BorderLayout;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;

public class UserInput extends JPanel{
	
	JPanel checkBoxPanel = new JPanel();
	public UserInput(){
		int noOfCBReq = Integer.parseInt(
				JOptionPane.showInputDialog("Enter the number of check boxes needed"));
		JCheckBox[] cb = new JCheckBox[noOfCBReq];
		for(int i=0; i<cb.length; i++){
			JCheckBox checkBox = new JCheckBox();
			checkBox.setText("Check box"+i);
			checkBoxPanel.add(checkBox);
		}
		add(checkBoxPanel, BorderLayout.CENTER);
	}
	
	public static void main(String[] args){
		JFrame f = new JFrame("User Input test");
		f.getContentPane().add(new UserInput());
		f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		f.pack();
		f.setVisible(true);
	}
}

Hope this helps

The other way would be to add a Textfield and a JButton. Make the user enter the number of check boxes in the text field and add a ActionListener to the JButton. Create checkboxes in the actionPerformed method of the listener.
Depends on what you want in the GUI...
