Simple Prototype Application for iOS, Android and Symbian

A hint at the beginning: You should be able to build this application for all three mobile OS! I want to offer a mobile application for the three operation systems iOS, Android and Symbian. The application itsself is very simple. It should make it possible to chose and paste two sentences from a sample and after that it can play that two chosen audio clips. So the app contains two scrolling wheels (please have a look to the attached screenshot) and the user can move the wheels by touching the screen. For example the user chose the sentence "you are so..." on the first wheel and the sentence "wonderful" on the second wheel. After that he press the play button and the app play the two audio clips one after one so the user can hear "You are so wonderful!" This prototype should only "run". No design or else is needed. If you make it run on the three operating systems you can complete this app including design in another paid project.
