Buttons that select playlists on a pc?

Ok, could anyone suggest a way of making an interface that has buttons with different moods on that opens up a playlist (prefferably in itunes) and plays it. for example, if I pressed the "Sad" button it would open up a playlist I have put together and play it automaticly.

Thanks 
:)

.  Save your playlists to the desktop (or other convenient place).
.  Double-click on a playlist as your mood dictates.

.  You may have to tell your OS to use iTunes to open playlist files. This may have been done when you installed iTunes.
