As far as I am aware, you cannot customize the MessageBox. You can
select from several different sets of buttons from the
MessageBoxButton enumeration, but those are all the choices you have.
I don't think you can rename existing "MessageBox" buttons because
their language must be based on OS language / version. You must pass
MessageBoxButtons enum to define which buttons to display on
MessageBox.

Additionaly, you can create a small dialog form to add fancy buttons
or custom text to behave as if it's a messagebox (actually not).

My recommendation would be to create a custom form.
