Weed control fabric doesn't really mean a maintenance free garden. You will need to rid the area of perennial weeds first. An industrial grade membrane can then be laid but you will still have the problem of airborne weed seeds which settle and grow in your gravel covering.
Impermeable fabric will possibly give you a drainage problem as you point out.
If you don't want to plant directly into the soil, perhaps some nice pots to break up the expanse of gravel ?
Whichever way you choose, be assured you will have to do some maintenance one way or another.
