Show form with page in background

[espfutbol98]

I've still been trying to figure out how to have an HTML form popup with the page in the background with a transparent png. An example is at http://java.sun.com/javase/downloads/widget/jdk6.jsp. If you click the Download button, a nice login form will appear in the same window. Lightbox does something like this but I don't see how you can have HTML in it, just pictures. Another example of this style is on facebook whenever you view friends or send a message. I've looked through so much javascript code trying to find out how they do it. Can anyone show me a quick example please?

Use jQuery UI Dialog or ThickBox plugin.
