Blood Alcohol Calculator Application

We want to create a USA based blood alcohol calculator based on user inputs. The user will input how many drinks they have had of four different categories: Beer (333ml at 5% alcohol), Wine (125 ml), a shot (45ml at 40% alcohol), or a mixed drink with one shot at 45ml and 40% alcohol. The next inputs will be weight, gender and time since first drink. After pressing the compute button, the calculation will be completed and a blood alcohol percentage will be computed based on established formulas found online. The application will then indicated whether the person is allowed to drive based on USA limits of 0.8%. For the purpose of this project it is a simple proof of concept and working example, therefore we believe a simple .exe will be the simplest form, but are open to other ideas. We will need a disclaimer saying this is just an estimate and not official. The UI can be basic, but we would like something interesting.
