In theory there is no difference between theory and practice, however in practice there are many...

think so,

How familiar are you with electronics and SW development?
You need to do some both on Arduino and on your Android phone.

additional requirements:
- close the door too smiley
- send a secure code that differs per time => so if the code is intercepted during the day it can't be used in the night.
- learning mode
- multiple androids for one garage door (kids/wife/dog whatever)
- multiple garage doors with one application (code send depends on geo location)
- depending on time of day the arduino switches also lights on/off
- add timeslots when this app may work (e.g. it will only work between 06:00-23:00 over bluetooth)

I would start with
0) go throught the tutorial section of arduino.cc to learn about the platform
1) an Arduino opening the door
2) closing the door
3) learn about bluetooth & serial communication
4) develop the android app (might take several steps in itself)
5) merge both of them
6) think over the security algorithm
7) do 6 again smiley-wink
smiley-cool implement the security algorithm
9) test it

Yes but better use some relays because that separates the circuits.
