As far as I know, it is not possible to rotate the text on a button or rotate the button itself.
You can only change the height and width of the button.
I don't think you can even change the font used in the UI, so even a rotated font (if you can find one) won't work.
UI_PICT_BUTTON will allow you to have any image you want, but it sounds like that is not what you are after.
