[REQUEST] Centering Image Text

[slidingmike]

I'm not very good at centering but if any of ya'll have read my other topics i was running on a theme compiled of several things. I found this image on google and want to add text such as "Messages" When going to SMS App or "Music" when going into Ipod App.

Can anyone create these for me, Its really simple and i would do it, but like i said i'm not good at centering the text and my image creating skills is not above paint.

But anyways I need:
Messages
Music
Safari
Facebook
Cydia
Phone
Settings

I did not create this image and all copyrights are hold by the respective owner.

I appreciate whoever does this for me i'm just looking for something simple. I'll attach the Messages one I did.
