well thar be two ways to go mate-y. use the spell that you normaly would to summon and bind a demon, however you provide a body ready to go and give the bound demon control.
the second method would be ta make a basic set of commands an have the golem be "programed" to respond a certain way. i would say 2 shifts per command sounds bout right.
now no matter how ya make the golem move to your commanding grove, i imagen you'l be wanting it to have some nice things like strength and speed, toughness and such so youl need to imbune the golem with those things and each would add complexity.
lasty my apologies for the oddity of my speach, typing, the pain pills for kidney stones be potent and bob is currently talking like a pirate in james marsters voice.
edit: found this to help out with the making of the golem body. its a spell made by one of the playtesters found here

Type: Thaumaturgy, transformation
Complexity: 26; can vary depending on duration
Duration: One day
Effect: When the caster completes this ritual, he or she must pay one Fate Point. The caster then gains the ability to fly, as per the Wings supernatural power, for one day. Unless the caster has some training in moving aerially (reflected by an Aspect and/or stunt), the caster’s Athletics is considered Terrible (-2) for purposes of moving by way of flight.
Variations: This model can be used to gain any reasonable power, subject to GM approval. Fate Point cost is equal to the refresh cost of the power acquired
