Java SE (Java Platform, Standard Edition)

Hi :-)

I've been using jdk for basic academic work last year, but for my end-of-study work, I must develop a little museum guiding application for PDA with graphical, sound and vocal features (if possible with Text To Speech).

I am getting messed up with all the available technologies, so could you please help me out for choosing the appropriate one for my work?

What Java technology should I install on my desktop pc to write this multimedia application and test it "as if it was on a PDA"? How do I set up everything? Are there particular libraries for graphical, sound and TTS features?

Thank you for taking some time to answer me, I'm starting to despair ;-)
