You really don't need the gym but will need to invest in a good exercise bench and a set of dumbells going from say 15 lbs to 50. You aren't really going to get some amazing results in a month so don't kid yourself. Also if you want a 6 pack you need to lose all the fat from your midsection...to see those muscles you need to be 10% or less body fat. I've gone from 200 lbs to 165 lbs in about 3 months doing cardio/weight training/better eating and i have a very flat midsection now but not a 6 pack (more like a 2...lol) yet but i'm still around 15% body fat so will need a little more.
