Thanks for your reply. It is indeed true that there are more job openings in programming than in physics-related jobs pretty much everywhere. I don't have any courses or certifications in CS (besides the minor in my B.Sc.) but I guess I could point out that my grades in the CS related classes I took at my university were always a notch better than in physics, math or whatever else. I also worked as a teaching assistant for basic courses in Java and C programming, so I probably should mention that too.
