How do I add a button on other UI element to a Google spreadsheet?

[gssi via StackOverflow]

I want to add a ToggleButton to a Google Spreadsheet. I would like to be able to control the positioning and the text on the button. Is this possible?

If so, does anyone know of a good tutorial that covers these topics?
