Simple Program Needed

I need a very simple software program developed for a school assignment. I am creating a decision support system for deciding whether or not to "Fly" or "Drive" when going on a trip. I have a formula already created using an Excel spreadsheet. I need a simple executable program that will ask the user the questions, calculate the results, and give either a "you should fly" or "you should drive" response. The software can have a very simple UI. Here are the questions that will be asked/input into the program: 1) Flight Cost (ie: $300) 2) Total Travel Time (ie: 4 hrs) 3) Current Gas Price (ie: $2.40) 4) Miles to Location (ie: 500) (I'd also like a link to mapquest) 5) A sliding scale for what is more important , Time or Cost (ie: Time__1__2__3__4__5__6__7__8__9___Cost) I will give you a 10 rating, Thanks
