First, let's scold Ingrid for doubting that anyone can learn a new knitting skill.
BAD Ingrid! BAD!
Wuv you, Ingy!
Second, did you check out the videos for small diameter circular knitting on the Advanced Tachniques tab above? Amy shows you both the 2-circs and the magic loop methods.
When you describe your circular needles, there will be 2 numbers...the needle size (2's, 5's, etc.) and the length (16", 24", etc.)
I say GO FOR IT!
