Outlook style popup that fades slowly

How can we build a outlook style window that has fading effects? Every time a new email arrives, it pops up and slowly fades away. I need build something similar. Can we really make a JWindow translusent by setting the alpha somehow? I looked at the SwingX components, I could not find any that works this way. SwingX lets me set the alpha on a JXPanel but not on a window. So, I was wondering if anybody is working on this kind of window.

I think Jide has an outlook style popup window, but I don't know if
it fades away.
Anyway, you should have a look at: https://jide-oss.dev.java.net/

JNA is a very good start. At the Extreme GUI Makeover session at JavaOne, I'll show a cool effect with fading windows. Hopefully we'll release the code very soon ^^

Thankyou every one. I appreciate it. I will start looking into JNA. It looks very exciting.

In case JNA turns out not to meet your needs (?) here's the basic algorithm:
1. Grab a snapshot of the screen where the pop-up is to appear, place it in a buffered image
2. Draw your pop-up to another buffered image
3. Draw your pop-up to the screen
4. To fade: blend the pop-up image with the snapshot image you first took, with the snapshot nearly 100% transparent, then repaint the result to the pop-up screen area (use double-buffering to reduce flicker if you want). Then sleep for a few milliseconds and repeat, until the snapshot is 0% transparent (100% opaque).

Don't use Thread.sleep() as you'll block the event-dispatching thread. Use a Swing timer or look at https://timingframework.dev.java.net/
