Simple Game for Smart Phone

I have a software application with questions and multiple answers data base. I would like to have something simmilar to offer my customers for free to download to their Iphones and Blackberries. It should be a simple application with the title page where my company logo and web address be listed, the second page should ask to select the language, the next page should ask if user wants study or exam mode and the next page should display the first question of 20 questions randomly selected from let say 200 questions data base. After each set (20) questions the program should calculate the result. Each question would have 4 multiple choice answers. The result page should display the percentage, some text and option to quit or continue. When continue the next set of questions should appear. The option to select language can be optional and to simplify this game it can be hold in English only. I have all questions, answers and necessary text in 10 languages. Moreover, each question page should have a small picture or image.
