When I start learning programming I was "completely non-technical" too. Give your non-technical friend a few years and you will see what she can do if she is really interested in making games.
I bet you were in the same situation at some point in your life.
If you want to give her a constructive advice tell her that she can use JavaScript with Unity3D for e.g. I bet you will be amazed at how productive one can became when one is passionated about something.
Certainly, one's early experience skews one's perceptions - I was 10 or 11 when I was 'non-technical', my friend is 35 (and, knowing her pretty well, her skills are definitely not in the coding area).
