And you have the rest of the field behind you, which has long ago
abandoned zillions-of-arguments designs in favor of:
(let ((m (make-message-box)))
(message-box-title-set! m <title>)
(message-box-prompt-set! m <prompt)
(message-box-bgcolor-set! m <color>)
except less verbosely, thanks to pervasive inclusion polymorphism.
