First Java Program-Has Errors-simple GUI

[cc11rocks]

Hello everyone! I'm glad to be doing some "real" programming (or at least using a "mainstream" programming language). Here is my first Java program. It has some errors. If you could point out how to fix these, that would be great. I learned Java from the book "Java for Dummies", of which I have a copy sitting next to me. I have limited experience with programming including HTML, Autohotkey, and bits and pieces with other languages. I have taken a 2 semester's of computer classes.
Thanks,

PS: I'm sending this to my computer teacher in middle school.

import javax.swing.*;
public class Creepster extends JFrame{
	JLabel label = new JLabel("Hello Mr. Creepster");
	JLabel label = new JLabel("This is my first Java program.");
	JLabel label = new JLabel("I wanted to show you that I am learning Java and to thank you for teaching me.");
		
}
public Creepster() {
add(label);
setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
pack();
setVisible(true);
}
class Showcreepster {
public static void main(String args[]) {
new Creepster();
}
}

when I try to compile this (using the command line in Windows through javac filename.java), I get these errors:

firstappinjava.java:7: class, interface, or enum expected
public Creepster(){ //the carret thing is pointing to the C in 
 //Creepster
firstappinjava.java:9: class, interface, or enum expected
setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
//the carret thing is pointing to the s in setDefault...
firstappinjava.java:11: class, interface, or enum expected
setVisible(true); //carret pointing to the s in setVisible(true);
firstappinjava.java:12: class, interface, or enum expected 
} //the carret is pointing to the }
5 errors

Someone figured this out for me. Just one more error:

import javax.swing.*;
public class Creepster extends JFrame{
    private String s;
    private JLabel label;

    public Creepster() {
    s = "Hello Mr. Creepster\nThis is my first Java program.\n";
    s += "I wanted to show you that I am learning Java and to thank you for teaching me.";
    label = new JLabel(s);
    add(label);
    setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
    pack();
    setVisible(true);
    }
}
class Showcreepster {
    public static void main(String args[]) {
        new Creepster();
    }
}

The error is:

Exception in thread "main" java.lang.NoSuchMethodError: main

If someone could figure this out that would be excellent.
