crontab

As stated in the title, I have to write a simple script which should perform some typical agenda's functions. The script must use crontab. The functions are:

Creating a new appointment
Edit an existent appointment
Delete an appointment
List the appointment

I really don't have a clue how to do this, can you help me with some hint? Maybe a bit of sweet code?

Thank you very much, Abaco

EDIT: To be more specific on my question

Point 1: how can I edit a crontab thorugh ksh? How can I insert a new line? Can you link me some documentation or a bit of code about this?
