Running power to a Garage- Need electricians help?

I have a detached garage that is about 30 feet from my house. I want to run power to the garage. I plan on having a garage door opener, light, and 3 outlets. I dont plan on running any heavy equipment (maybe a small compressor). I though I could just bury some romex in 1.5″ PVC pipe but I was told not to use romex as it is designed to run in a certain heat range.
I dont plan on using a sub-panel in the garage.
So here are my questions?
-How deep does the wire have to be buried?
-Would 12 gauge wire on a 20 amp breaker be sufficient or should I go with 10 gauge?
What are my options on burying the wire? What tipes of wire can be run in PVC and buried underground?
Any other tips would also be appreciated.
Thanks!
I have considered a sub panel but think it migh be a bit beyond my capabilities… also, its a good 100ft run of wire to the garage. 6 gauge might turn bout to be a bit pricey.. copper is expensive.
Do most recommend me using a sub-panel?

Some good idea’s But they seem to have forgotten the NEC, If you run UF or URD(direct burial wire) you have to be 24″ deep to the top of the conductor, If you run it in PVC you have to be 18″ deep to the top of the conduit, you would be better off to put a sub-panel for a 60amp panel you would need either #6/4 UF for direct burial, If you ran PVC you would need #6 THWN x 3 strands and a #8 THWN for the ground, you need to keep in mind that if you set the sub Panel you have to also drive a 8′ ground rod, with a #6 solid copper bare ground, If you run a couple of 20amp circuits to it instead, they have to be GFCI protected and if you run more than one 20amp you would also have to drive a Ground rod and run a #10 Ground to it from the J-box you set in your Garage If you do one 20amp circuit you don’t need a ground rod…I hope this gives a lil more info
