Looking for a Quick and Easy Tool to Export Coordinates for a Interface Layout

Basically I just want a tool where I can setup all my art assets on a screen and it can give me the coordinates to use in Corona.  Im not looking for a real level designer.  Just want coordinates to where the images are located.  Another example would be for my title and credits pages.  Im sure there is an easy way to do this, just wondering. 

Thanks,
Scott
