Hi Mike,
Seconding Sherm and Joar, this will be the easiest way to get started. Down the line, if that doesn't work, have a look at Core Text.
Also, I have been developing an application for drawing with text. I draw a few hundred individual letters at a time, then commit them to a graphics context so that the next time the whole view is drawn, one context is drawn rather than 1 context + n letters.

If you find that it doesn't perform well enough, use your measurements to guide you to a better implementation. I don't think that we have enough information yet to provide really good suggestions.
