@{Adds an Ok and a cancel button to a panel, changing the order
to suit the platform. Under Mac OS X and unix, the confirmation action
is on the right (or bottom) and under Windows, the canceling action is on
the right (or bottom).
The confirmation action button has the @scheme['(border)] style.
The buttons are also sized to be the same width.
The first result is be the OK button and the second is
the cancel button.
By default, the confirmation action button has the @scheme['(border)] style,
meaning that hitting return in the dialog will trigger the confirmation action.
The @racket[confirm-style] argument can override this behavior, tho.
See @racket[button%] for the precise list of allowed styles.
See also @scheme[gui-utils:cancel-on-right?].})
