	I think it might help if you are a little more specific about what 
features of GAMS you are looking for. For example: Set based modeling, 
Non-linear support, Access to external data sources, etc...
Or are you looking for a language that will emulate closely GAMS' syntax?

My immediate interest is in the set and looping capability of GAMS for
linear and mixed integer programming.

And I would like to be able to emulate as much of GAMS language and
functionality as possible.  All leading to, as Alan has said, the concept of
open interfaces to language and solvers of choice, access to data
structures, etc.

A process something like:

  modeling language (ML) of choice =>
  ML parser =>
  COIN-OR language =>
  compiler =>
  object code instructions =>
    prepare data and other model elements
    while (!done) {
      send model to solver
      extract data
      prepare/interpret/modify data as desired
    }
