This occurs because the tuning of any keyboard instrument represents a compromise between the true temperaments of the 12 different root tones available in Western music. In effect, there are two choices which can be made: either you can tune one particular scale (such as A) in its true temperament, and accept the effect this has on the other scales, or you can compromise and tune all the notes a little off, which results in no scale being exactly in tune, but also no scale being so badly out of tune that it grates on the ear. This system is known as the even- or well-tempered system, and is the motivation for Bach's set of propaganda pieces known as \\Die Wohltemperierte Klavier// (lit. \\The Well-Tempered Keyboard//, meaning "keyboard instrument". The result of using even temperament is that some notes are a bit sharp, and some others are a bit flat, and which notes are which vary depending on the scale you choose to play in. This purely physical effect has a great deal to do with the psychological effects noted above. More information is probably available in a good book on piano tuning, or possibly in some music history books. I also think there was an article on piano physics sometime in Scientific American. If you have their "Physics of Musical Instruments" reprint collection available, it may be in there. As far as playing in keys with lots of sharps and/or flats being difficult, you'd have to talk to a pianist about that. Speaking from my own limited experience, the problem is more along the lines of remembering which notes are to be sharped or flatted than actually hitting the notes. Once you know how the work is supposed to go, this problem tends to take care of itself.
