Playing sound using quicktime package?

Question

I'm trying to make a very simple program (actually, part of a much larger program) that can play a sound file. Nothing else needs to happen during that time, and no other sound file will be played at the same time, so hopefully I'll be able to avoid threads, mixers, and all the rest of that stuff.
After not being able to make head or tails of all the extremely complicated tutorials on Java Sound, I finally found some very short code that allows me to play a .wav file, just like I'd want. My only concern is that it uses the quicktime package, instead of the Sound package that everyone else seems to refer to.
In particular, it seems to be treating the sound file like a movie. Here's some source code:
import quicktime.*;
import quicktime.io.*;
import quicktime.app.time.*;
import quicktime.app.view.*;
import quicktime.std.movies.*;
import quicktime.std.*;
// Lots of GUI interface stuff
    public void playFile (String fileName) {
         try {
            String soundLocation = QTFactory.findAbsolutePath(fileName).getPath();
            OpenMovieFile fileIn = OpenMovieFile.asRead (new QTFile(soundLocation));
            movie = Movie.fromFile (fileIn);
            TaskAllMovies.addMovieAndStart();
            movie.setActive(true);
            movie.setRate(1);
           } catch (IOException ioe) {
                ioe.printStackTrace();
           } catch (QTException qte) {
                qte.printStackTrace();
    }Does this seem to be all ok? Will the computer the program is running on need QuickTime, or is that completely different? Is this as fast as using Java Sound?
Sorry for the possibly silly questions. Normally I'd say "I've tested it, it works, so that's all I need", but I got a little bit worried seeing "quicktime" and "movie", and wondered if this is what I really should be using.
Thanks!

Also-- something to think about. You may be able to
avoid threads while the song is playing-- if you
never want to stop it, pause it, or do *anything
else* within the same GUI -- assuming you're using a
GUI.
Hope something in the above helps.In this program the user doesn't get to control the sound while it is playing. The program is an assesment of language comprehension engine for my lab. The user hits "Go", the sound plays (all 2-3 seconds of it), then the user hits "yes" or "no" depending on the sound.
I'm only just starting to code this. Do you think it's going to need threading? I can't imagine that it ought to take more than 5-10 lines of code, but those Sound tutorials made it seem like I'd need 100.
As for playing a "movie", that's why I was worried. Taking a deeper look, it seems like Apple's Developer website is promoting using the QuickTime package, but I haven't yet worked out how compatible it is with other file systems, and whether it's as good.
Thanks, and any other thoughts are welcome!
