If you only want ground-fault protection, you need no grounding wire. Just install the GFCI receptacle. It won't be grounded but it will work just fine as a GFCI.
If you require true grounding, and I don't really know why you would, then run a cable down from the attic into the wall where you want the receptacle. Run that cable through the attic to above the panel, and then down into the panel. Install a new breaker in the panel for this receptacle. Install an old-work box where you want the new receptacle. Use 12/2 cable and a 20-amp breaker. If your attic gets really hot, you might need 10/2.
Obviously there's a lot more to it than that. Get a book or two on home wiring from your public library or home improvement center. These books cover this kind of a project very well. Consider having an electrician do the work inside the panel.
