Styling buttons as Dialog buttons

Hi everyone,
I realy like the JQuery UI "Smoothness" style and effects. So I will
to set the style of my buttons "<input type="submit|reset" />" and
"<button />" as they are un the "Smoothness" theme.
Of course I can make many "reverse engineering" to discover styles and
effects applied to the buttons but maybe is it another way to achieve
that.
As somebody already extracted styles and effects from a JQuery UI
theme and applied it to all his website ?
Thanks
