width here is only ONE object

Here all your lines are the same object (not copies).
It will work ok if you do :
for i in range(30):
Board.append(width[:])
here ^^^ you are assigning a COPY of width
Or you might check :
Board = [['- ' * 30 + '-']]
for line in xrange(30):
Board.append(['|']+[' ' for i in xrange(59)] + ['|'])
Board.append(['- ' * 30 + '-'])
Board[2][3] = '+'
for i in range(32):
print ''.join(Board[i])
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
