Cross-Platform Case Based Physician simulation program

**SUMMARY OF PROJECT** In order for physicians to get licensed, they have to pass a test called the USMLE Step 3. Part of that test has a computer program that simulates patient who present to the Emergency room or office with symptoms and complaints. The user of the software program has to enter orders and lab tests to manage the patient. They will be graded depending on how well they manage the patient. The purpose of this project is to develop a computer program that mimics the testing environment to provide practice for the students that are going to be taking this test. The company provides a practice test that only has 6 clinical cases. The program will eventually have 100 cases (but will start off with 50 cases to start). The program should be as close to the real test as possible. The practice software included in the link below should be the guideline. The program should work exactly the same and the practice software so that the student will be familiar with the software on test day. **What language should this be coded in?** The requirements for this project needs to be cross-platform. It needs to be a stand-alone application, or if it's web-based, it needs to be able to be put on a CD, and install to sell. I am open to suggestions. It can be programmed in java, Silverlight, adobe air, html5, or any other cross-platform. I would like to discuss this further. If you feel that another language would be more beneficial, I would be more than happy to discuss this. Attached in the word document is an extremely detailed overview of what is required in the program
