You can just use the text tool. The font is Verdana (I'm pretty sure most computers have it, if not download it), size 7, and the colour should be #E8E8E8. It says this on the first post, by the way 
I would really recommend using this tool though. It makes sure the text is properly aligned and everything, and makes consistency much easier as it's less prone to human error. The only real reason to make them by hand would be if you want to make some really fancy icons, but even then I would use the Icon Maker to create the border.
