Using today's experience with today's live game, yeah easily done in 2 weeks. Using vanilla WoW's experience, nope. 2-3 months was the average time it took for someone to level up a fresh character to 60 back then. The only people who had a level 60 in a month or less were people with no job, school, relationship, or life who played 18 hours a day. Assuming you have at least 2 of those things I listed, you'll be hitting 60 in about 2 months.
