Final Fantasy IX skill learning system.

Does anyone know, or can make, a script that would make an ability learning system similar to that of Final Fantasy Tactcics, or Final Fantasy IX?

Details
~Each weapon would have an inherit ability on it, such as Fire or Blizzard.
~A charecter could use the ability when the weapon is equiped.
~After a battle, each charecter would collect AP.
~When enough AP is earned, the charecter would learn the ability, allowing he/her to use the ability without needing the weapon.

Note
I really woulden't mind variations that much, such as the ability can only be used when mastered, or use # of battle instead of AP.

Hope someone knows this,
