Does the Catholic Church prohibit marriage between a woman and her God-father?

Each child born in a Catholic family, receives the Sacrament of Baptism at an early age, and is escorted by its Godparents at the time of its baptism. Traditionally, a godparent must normally be an appropriate person, at least sixteen years of age, a confirmed Catholic who has received the Eucharist, not under any canonical penalty, and may not be the parent of the child. Now, there could be a situation in which a Catholic girl grows up and develops an affinity for her Godfather in spite of the age-difference of say, twenty years. They are not related to the extend that their union is prohibited on the basis of proximity of blood-relationship. Does the fact that they are Godfather and God-daughter, stand against their receiving the Sacrament of Matrimony ? In other words, does the Catholic Church prohibit marriage between a woman and her God-father ?
