Pop up a dialog screen and allow user to pick a selection

This is a simple example of displaying possible choices for a user. The following code prompts the user
for a operating system/platform. Upon the user making a value request, a dialog screen pops up with
possible values listed. The user can then select from the dialog screen. Adjust to your own needs. Enjoy!
