Could I learn French or Italian in a year?

Okay I am going to Europe next June and spending three weeks I am going to Rome and Paris and I want to be able to interact with the natives I keep hearing that it's impossible to learn it in such a short amount of time but I think I can pick languages up fairly good five months ago I could not get a German sound out of my mouth and just by listening to a German band I can speak with a German accent and can pronounce the words fairly easily I know am rambling but how fluent could I become in eleven months?
