First, thanks to Dr. Mark Lewis, the professor who taught me Scala. This tutorial is a result of an assignment for one of his classes.
Next, thank you Jim McBeath. He has a short explanation on his blog regarding how to write a Scala web applet, which can be found here. His blog post was my main resource when figuring out how to make a Scala web applet for the first time.
Lastly, thank you to everyone who has contributed to this tutorial by sending in suggestions and by providing content for the Troubleshooting section. Keep the suggestions coming!
