If you're OK with channels (for me they feel different from casted spells), then Mistweavers pretty much do nothing but instants and channels. And they have a 1-second GCD for their instants.
If you don't like channels, druids spend the least time casting, but most of what they do is HoTs.
If you don't like HoTs, disc priests have the fastest cast time on their filler spell, but it's a DPS-based smart heal.
If you don't like DPS-to-heal, paladins have the most instant traditional direct heals, but they do regularly cast several slow spells, and you have to be OK with the Holy Power mechanic.
If that still doesn't appeal to you, shamans have the fastest cast-time standard direct heals, but they spend the most time casting of all healers.
