MilesBuzz! - Program for writing itineraries

Does anyone know of a program that allows you to write your own itineraries.
I have to submit mine to quite a few people in my co., and have to supply meeting details etc.
Something alittle more presentable than microsoft word maybe?

Since this isn't about miles and points, I'm going to move it to TravelBuzz (http://www.flyertalk.com/travel/fttravel_forumcgi/forumdisplay.cgi?action=topics&forum=TravelBuzz!&number=11&DaysPrune=5&LastLogin=).

Best,
