Planetary gravity question.

Given the knowledge that many listmembers seems to
posess, I hope you might be able to help me with
something... :)

Would a planet the size of our moon be able to attain
a level of gravity that Earth posseses?
If so, could it be habitable? (Possibilities for
fertile soil etc...)
Could it be a fully fledged eartlike planet?

I'm fluff writing, hence the question. :)
