Write a simple Reed Solomon Calculator Program

I'm looking to have a program developed which can detect a reed-solomon sector from a group of 512 byte sectors sampled from individual members of a RAID array. The intent of the program is for determining parity rotation in failed RAID 6 arrays. The program would need to have a basic GUI with the following functions: 1. Option to select number of members in the array from 4 to 16 members 2. Based on number of members, have boxes in the next screen to paste in values pulled from same sector of each RAID member (preferably as GREP expression, but other ways such as ANSI might work too as long as it's a format which can be copied from a hex editor such as winhex). Once all values are pasted in, have a "Calculate" button to be pressed. 3. Program will then brute force calculate reed solomon value for every possible combination of the sectors (less two for the P (XOR parity) and Q (Reed Solomon) members) and check that value against the remaining values pasted in to determine which one is the Reed Solomon sector. This can all be done under the hood, no visual output required. 4. Program then indicates which of the sectors was the Reed Solomon, and which other blocks were used to calculate it (so the P block can be indicated as well). This project will require the programmer to have good understanding of the math involved with reed solomon calculations. The program doesn't need to be "pretty", just a basic interface to put in the values and get the results back as well as some basic logo branding.
