To get a PPL you must first go to kindergarten before you enter grade school.
Kindergarten would be held in a farmers grass field and the school room would be a Cub, once the student mastered the Cub to solo they would then enter grade school....a regular flight training school where they would then be taught by rote and introduced to all the ancillary tasks such as radios, flight and engine instrument interpretation, weather and on and on until they either realized they were being screwed or they go broke.
This is almost precisely the wrong way round. Start with a PA 28 or a 172 or some other half way sensible but cheap aeroplane which is easy to fly. As soon as the pupil can land reliably send them solo and then teach radio, GPS and all the other bits that make travelling in a light aeroplane practical.
Thereafter you can do advanced things like flying old aeroplanes that are hard to fly and aerobatics and so forth.
