Does the Catholic canon law say anything about women being priests? Is there any canon law in the Catholic Church about the role of women in the church and its possibilities to be groomed for Priesthood?
Can.  1024 A baptized male alone receives sacred ordination validly.

The Code of Canon Law makes it clear that only a male can be ordained validly. This is teaching of the Church going back centuries and most recently outlined by Pope John Paul II in Ordinatio Sacerdotalis

The priesthood being only for men doesn't mean women have no role. Not all men are eligible to be priests and not every man desires to either. There are many roles for both men and women, some are exclusive to one or the other and some are for either. 

Men can be priests (and bishops or cardinals or popes), but also monks, friars, altar servers, teachers, professors, hermits, fathers, etc.

Women can be nuns, religious sisters, teachers, professors, mothers, hermits, consecrated virgins, etc.
