Given her background, I could easily imagine Seven developing an infatuation for Janeway. As far as I know, Janeway was always portrayed as straight, so it wouldn't be reciprocated.
Even if Janeway were interested in pursuing a relationship, I rather think she'd be too aware of the ethical issues involved. Seven could probably be classed as a vulnerable adult, and as such it would be inappropriate and immoral for a guardian figure to get too emotionally involved.
