A 'choose your Colour' application

I want an android app that lets people choose 2-5 colours and randomly selects one of the chosen colours to be the ‘winner’. The is called: 'Choose Your Colours' The start page will display 5 colours in blocks (See supplied image, Picture1) and a ‘GO’ button. The user has to select 2, 3, 4 or 5 of the colours by pressing the coloured blocks (These blocks will light up after selecting the colour: See supplied image, picture 2 [in this picture blue and green are highlighted]). When 2 or more colours are selected, the ‘GO’ button lights up and can be pressed. When this button is pressed it disappears and the circle in middle of the page lights up and displays the number ‘3’ after one second, number ‘2’ and one second later the number ‘1’ as a countdown (See supplied image, picture 3). After the countdown, the randomly selected ‘winning colour’ page shows up (See supplied image, picture 4). This page has a ‘Again’ button in the place of the ‘Go’ button, and the rest of screen is in the randomly selected colour. The app also needs an ‘info’ item when the android menu button is pressed. The info page is plain white and has the following text: “To play this game please select two or more colours by pressing the area in the colour you wish to select. When two or more colours are selected, the GO button may be pressed. After pressing the GO button, the app will count down from 3 to 1 and will randomly select the winning colour. By pressing the AGAIN button, you can start over.” On this info page, there also needs to be a button (‘PLAY’) to go back to the starting page.
