I’m an average Visual Studio programmer. I need a function or routine to add text to the button of an image not on it like I showed in the image

Ideas please.
[Edit]
- Am programming with visual studio
2008, on winxp. - The application is a console app.
- it will run on win2000 upwards
- i will save the result image after
adding text to file
Create a bitmap with the new size you want
Copy the original image at the top of the new bitmap
Write the text you want onto the new bitmap
Something like this: (untested)
