Okay, this should be fairly easy actually. I apologize but Im not really familiar with the pronto remotes, we use rti and urc.

When you program your 12v triggers, can you set them to pulse(quick 12v output then goes dead), latched(maintains 12v until second command to release), or timed(12v output for selected time, then goes dead)?

This will determine if you will need a seperate actuator control or not.

This is a good project to start with. It will be fairly easy to accomplish without a ton of $$$. Let me know on the triggers and then we will be good to go. (I get excited about these projects even if there not mine!)
