Gromov-Witten theory studies symplectic manifolds via maps of Riemann surfaces into it. In contrast to the fundamental group, where one studies maps from the circle into the space, there is no composition law for Riemann surfaces. Instead, one considers pseudoholomorphic curves in a fixed homology class and with fixed boundary conditions such that only a finite number of such maps exists. These numbers are symplectic invariants. Their computation is difficult and uses enumerative and analytic techniques from Floer homology.
Gromov-Witten invariants are used to deform the cup product of cohomology classes (using only maps from the Riemann sphere into the manifold), leading to quantum cohomology.
Gromov-Witten theory originates in physics from the A-model. A powerful tool to compute Gromov-Witten invariants is mirror symmetry.
The precise mathematical definition uses the notion of the moduli space of stable maps.

Gromov-Witten invariants may be understood (and have originally been found) as arising from a particular TQFT, or actually a TCFT, called the A-model.
For a useful exposition of this see (Tolland).
