Where there is an electric charge there is an electromagnetic field and thus photons.
Where there's a mass there's a gravitational field and thus there are gravitons.

They work, but the Math is much more complicated. There are fields where the mediating particles carry the "charge" of the field themselves. They are called "Yang-Mills" fields. (This is not true for EM...photons carry no electric charge. QED, the quantum version of EM, is relatively simple for that reason.)

(shrugs) It has a field, in quantum terms it is an interaction, so it's a force by definition.
