For someone her age and also a beginner, I would recommend either Bare Escentuals Bare Minerals, or Clinique. Both offer the most natural look and both are excellent for sensitive skin, won't clog pores, and are easy to apply. MAC is also great but their line gravitates more toward vibrant, flashy, dramatic looks...not quite so soft and natural (not that you can't achieve a natural look with MAC, it's just more pigmented in general).
I would book your daughter for a free makeup consultation at the Clinique counter in department stores where they will match her skin tone with a foundation. They can also help her select a natural blush (if she wants one), powder, etc. To present it as a gift to her, you can purchase a few makeup brushes in advance like a foundation brush, blush brush, powder brush, and eyeshadow brush. You can probably even buy her a light neutral eyeshadow duo that you think would compliment her eye color (and that you approve of!). If you're interested in her skincare routine as well, they have a 3-step program that is wonderful. The online tool asks a few questions about dry/oily skin and assigns a number (1-4) of her skin type and shows you which products are for her skin type. You could buy those in advance also.
