Golden Ticket Number Generator

We need an application writing that will create a random number generator. The system will be used to come up with a number that people with raffle tickets will watch. We will provide the logos to be put into the program so it is branded to us. We need the ability to put in a number (such as 999, 499) and then the system randomly chooses a number in the range 0-(That Number) and then shows the output in a very tidy way! Each person who visits will be given a raffle ticket and then at the end of the evening the golden ticket will be shown. The program needs to show the number in a 'cool' way such as a fruit machine coming in, or other numbers first before slowing down to show the final result. The program needs to be simple where all we do is put in the total amount of tickets i.e. 999 and then click start, this should take you through to a further screen which then will display the result when the button is clicked. Thanks
