Please show me how to make a java box pop up and display information!

Question

Hey people, Im trying to design an organiser in java using netbeans for a project. Iv made the initial GUI which is a box that loads up and it has my logo on it and below that a lable saying Personal Information. It has a View button next to it (iv named the variable view1 and it is a JButton)
Im finding it really difficult to do. What i would like is another box that pops up allowing the user to enter their name, address, date of birth, current school year and car registration, and store the data entered into a text file.
If anyone could help me with the code i would be really greatful, it would also help if you could comment next to the important code to help me understand whats going on.
I would really appreciate it guys. thanks

            panel.add(new JLabel(labels));
panel.add(fields[i]);
// allow the user to fill in the fields
if (JOptionPane.showConfirmDialog(null, panel) == JOptionPane.OK_OPTION)

for (int i = 0; i < returnStr.length; i++)

else
return null;

for (int i = 0; i < info.length; i++)

catch (FileNotFoundException e)
e.printStackTrace();
finally
if (pw != null) pw.close();
public static void main(String[] args)
Foo f = new Foo();
String[] results = f.getInformation();
if (results != null)
f.writeToFile(results);
