Don't underestimate the challenge of learning french for beginners. It may not take too long to be able to say hello and goodbye, but if you want to be able to communicate anything useful, it is going to take practice. Repetition is the key to remembering new words and phrases.
At first you will be mentally translating all your words from English to French. But with enough practice, you will start to skip the mental translation process, and you'll be able to speak or respond fluently in basic situations. It's a good idea to listen to French radio or watch French television shows, if they are available. Even if you don't understand ninety percent of what is said, just hearing French will get you familiar with the cadence and tones of the language. A new language always sounds like undifferentiated gibberish in the beginning, but the more you listen to it the more you will pick out separate words.
