App dev. ipohe ipad app. handheld

Good day, I would like to create a simple iphone ipad application of a Valentine greeting card. 1. Card background is "royal-pink" color 2. a border-hollow "heart-shape" in the centre of the greeting card - the border of the "heart-shape" is chilly-red in color and about 10cm or whichever fit better. 3. insert creatively "Happy Valentine Day" inside the heart-shape - "Happy Valentine Day" is chilly-red color. 4. tiny rose-petals is dropping around the card but NOT inside the heart-shape - rose-petals is semi pinkish-red color. 5. the heart-shape, Happy Valentine Day, rose petals and the card should be outstanding to attract soft affection and joy. Thank you
