It depends on what your goal is. If its simply to communicate it does not have to take that long sure it will be very broken
Me hungry me eat instead of I eat when I am hungry but as long as you get the message across you have succeded with communicating.
You can. Step 1 find a group that welcomes non language speakers. I used mmos to try. Can also just have 1 person. But I find guilds better since you get more exposure. Step 2 ignore grammar and just caveman it. Why many word when few work. Then when you no longer need google translate to understand and to talk learn grammar. Language is a tool for communication so focus on being understood before proper sentence and conjugation.
