buying tools

[Porkchop]

I have a 69 chevy and it is very very rusty. I found that there is no way I am throwing my shiney rebuilt engine into a rusty truck. So, I really need a way to weld. I have an oxy-acetyline torch that is very handy for cutting rusted bolts and stuff. I would like to be able to weld though also. I know it is possible to weld with this torch set up, but will it work for the body panels for my truck. I am not a profesional and have neverwelded with this torch. I hear it is tough, but do you guys think that if I read up on it I could teach myself to weld? If it would be too hard to weld with this torch, what would be the cheapest welding setup that I could buy that would work for what I need it to do?
thank you all very much
