Using regular buttons in place on radiobuttons

Hi everyone,
is there a way to customize radio buttons to look like a regular rectangular button with text embedded in it.

here is a link of a much more detailed explanation of what i’m trying to get at.

the program works fine with radio buttons, but for aesthetic purposes i would like a different look to the buttons.

thank you for any help on this.
