To avoid the tit for tat:
To tow gliders you need training and an endorsement by an appropriate person.
You need some glider experience before a club will do said training.
The towplane does not need to be a taildragger, Cessna 150s with 180HP and C182, Robins, Rallyes etc. have been used.
That said, tailwheels are much more common, Piper Pawnee 235s would be the most common tug in OZ.
Go for it!
