I know of 2 ways to make a button out of text.

1. Make the text, convert it to a button symbol and then assign the parameters.

2. Create a rectangle the size of your text, convert it to a graphic symbol and set the alpha to 0, then put the text over it, select both and convert them to a button graphic and assign them getURL parameters.
