Build a Bejeweled-like Match-3 Solver.

Hey there, I need a stand-alone program that allows me to input tiles in a grid, which will then give me the ideal solution for the largest match, and best matches after those tiles are filled in with tiles above/below. Bejeweled is the exact type of game I am talking about. - I must be able to change the grid size (6x6, 7x7 and so on). - I must be able to add tiles myself in up to 6 colours. - I must be able to add inert tiles, that cannot be matched. - Any language can be used, as long as it is stable and consistent. - It does not need to look good, as long as it is relatively easy to use. No hacking of accounts is needed at all. This is intended for single-player games only. The program does not need to control or click anything on my behalf, just show me the ideal move. I will not sell the program. Questions are welcome. Thanks.
