Hey Incendie,

Using the ingame macro system, you can perform what oyu want by writing an addon, however it would only work while not in combat.
This is due to teh restriction of requiring direct user input to trigger a spell.

For using a program to accomplish this, it is currently considered a grey area (using mouse clicks -> keyboard replication). While possible it is currently unknown if this will be considered allowed under the ToS.
