There are far more self-taught guitar-players than pianists; they may not be very good, but they can make an acceptable sound, whereas self-taught pianists are likely to sound pretty awful. So there's your answer!
That is pretty difficult to answer because there aren't many comparisons between the guitar and piano(trust me I know how to play them both).In different ways it's harder and easier,a piano is harder to master than a guitar,playing a guitar you must have great precision,On a piano it's ok to use your thumb,on a guitar you could get carpal tunnel if you use your thumb too much. The answer to this question is:piano.
it is not easier or not, it is more about what you like and what makes you comfortable because if you like one but you are not comfortable with it, you are going to have hard times otherwise if you are comfortable with it, you will enjoy it and won't find it hard!
but from another point of view i think piano is harder than the guitar because you are dealing with many buttons in two hands despite guitar dealing with several tendons with both hands...
The easiest way to self teach and learn to play piano is to buy a piano or a keyboard, learn some basic musical knowledge and start practicing easy songs. Alternate ways are to learn from CDs, DVDs and books or to hire an instructor.
Well, you can start by buying some piano books for beginers that teaches you about the keys and scales and solfedge. There should also be some practice songs in there too.
they are both equally difficult

Guitar and Bass Guitar, sometimes slide guitar, drums, keyboard/piano, even percussive instruments
guitar, vocals, synthenizer, keyboard, violin,
A bass guitar is easier than playing a guitar or drum set or keyboard while singing. But singer/keyboard player is a very common combination.
I think a keyboard is easier to learn and more logical than learning guitar chords. Guitars have a certain coolness and of course many teen idols play guitar like Sweet Baby James.
