Alright, I've been working on the prog a little, but I'm still unsure about how to draw the actual calendar days itself. Here's the code:

Code:

import java.applet.*;
import java.awt.*;
import java.io.*;
import javax.swing.*;
import java.awt.event.*;

public class BirthdayApplet extends Applet implements ActionListener
{
    public static int WIDTH=500, HEIGHT=500;
    private Button displayButton;
    private TextField monthField, dayField, yearField;
    private AudioClip myAudioClip;
    private int inputMonth, inputDay, inputYear = 1, dayPrinter = 1;
    private int firstDayofYear = 2, firstDayofMonth = -1, firstDayofWeek = 2;
    private String year = "", days = "";

    // Creates arrays to store the days in the month and their names.
    
    int[] daysINmonth = {0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
    String[] monthNames = {" ", "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};
    int[] daysINweek = {0, 1, 2, 3, 4, 5, 6};
    String[] daysOFweek = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
  
    // Initializes the applet
    
    public void init()
    {
        setSize (WIDTH, HEIGHT);
        
        // Plays 'Happy Birthday' Song
       
        myAudioClip = getAudioClip(getCodeBase(), "../../audio.mid");
        myAudioClip.loop();
        
        // Creates the textfields, labels, and buttons.
        
        displayButton = new Button ("Display Birthday");
        displayButton.addActionListener(this);
        monthField = new TextField (2);
        dayField = new TextField (2);
        yearField = new TextField (4);
        Label monthLabel = new Label ("Month");
        Label dayLabel = new Label (" Day");
        Label yearLabel = new Label (" Year");
            
        // Adds the buttons, labels, and textfields to applet.
        
        add(monthLabel);
        add(monthField);
        add(dayLabel);
        add(dayField);
        add(yearLabel);
        add(yearField);
        add(displayButton);
    }
    
    // Determines if the input year is a leap year.
    
    private static boolean isLeapYear(int year)
    {
        if(((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0))
        {
            return true;
        }
        else
        {
            return false;
        }
    }
    
    // Finds the Julian Day equivalency of inputs.
    
    private int getDay(int month, int year)
    {
        int jday = 0;
        for (int i = 1; i < inputMonth; i++)
        {
            jday = jday + daysINmonth[i];
        }
        jday = jday + inputDay;
        return jday;
    }

    // Finds which day of the week birthday falls.
    
    private int getDayOfWeek(int jday)
    {
        return (jday + firstDayofWeek - 1)%7;
    }
    
    // Paints calendar and leap year (if applicable).
    
    public void paint (Graphics g)
    {
        if (isLeapYear(inputYear) == true)
        {
            g.drawString("The year you were born was a leap year!", 140, 400);
        }
        if (inputMonth > 3 && inputMonth < 8)
        {
            g.drawString("   " + monthNames[inputMonth] + " " + year, 205, 200);
        }
        else
        g.drawString(monthNames[inputMonth] + " " + year, 205, 200);
        g.drawString(days, 170, 225);
    }
    
    public void actionPerformed(ActionEvent e)
    {
        if (e.getSource() == displayButton)
        {
            // Converts inputs from strings to integer values.
            
            inputMonth = Integer.parseInt(monthField.getText());
            inputDay = Integer.parseInt(dayField.getText());
            inputYear = Integer.parseInt(yearField.getText());
            year = "2008";
            days = "S     " + "M     " + "T     " + "W     " + "T     " + "F     " + "S";
            repaint();
        }
    }
    
}
