Welcome to the JPF! You will find a lot of like minded folks here. The way to get started? -- Get involved and stayed involved. Comment on other people's tunes and they will comment on yours (that's the way it works).
Learn to play an instrument -- you don't have to be great, just be adequate to get your musical ideas out there. If you don't play, then in one year of playing guitar fifteen minutes a day, you will be better than 90% of all the other players (ha, ha). There is no easy way, no magic bullet. Today is just the first day on the long (but exciting) road ahead.
