The AIMMS software package provides a user-friendly way of building and editing MILP problem definitions.
It produces a problem definition in a standard format (e.g. .mps) which is passed to a solver (e.g. IBM CPlex) which is included in the distribution.
AIMMS is available here. Trial licenses are available. Academic licenses are free upon registration (the registration process seems to be broken, if you receive no response within a few days then email them).
