how can i learn greek?

i would like to learn the basic greek grammar, like verbs and tenses (specially the present progressive, past and future)... thanks!

i'm trying to learn greek, i'm not in a class and i need a website or software program that will help me learn the language. like greetings, verbs and conjugations, adjectives, and pronunciation.

thanx in advance

If I learn 20 words everyday , 10 verbs everyday, and learn reading and writing in Greek, how much time will it take for being able to speak with someone, watch a movie,et?

And can you advise me a good website, possibly with audio examples (for prununciation and accent) ?

Do you think 3 months is enough?

Thanks
