So every element of the resulting vector will hold the intensity of a 1Hz bit of spectrum?

No, not at all. The N-Point DFT gives you N evenly spaced frequencies that make up the whole Nyquist bandwidth (i.e. the sampling rate in the complex case).

Also, you mentioned what would be in X, but what should vector W contain?

is the DFT Matrix. Look it up. The wikipedia Article is very illustrative with great visualizations!
