Easiest way to achieve a radial gradient?

Hi guys.

I'd like to have a kind of dreamlike effect on some images I'm rendering, whereby a central oval on the rectangular display shows the image with complete clarity, but once you've passed the oval boundaries and continue to move outwards, the image pixels fade to white at some arbitrary rate.

Is there any straightforward way to achieve this effect? I've looked at java.awt.GradientPaint, but it's only useful for linear gradients =(

Thanks for your time.
