The proper way of doing this is, believe it or not, with a customized slide control. It looks like radio buttons and outputs the number of the option selected.
Attached is a VI showing two I put together. To use them use the text control at the bottom of the control to set the name of the buttons, or add new ones by adding items to the list.
Once you have the items configured, right click on one of the buttons and select Visible>>Text Display to hide the text display and you're read ro rock and roll.
