I'm not sure with which language you will use GD, however, these
operations are quite easy to do with GD:

- open the PNG image file (gdImageCreateFromPng)
- draw your text (gdImageStringFTEx)
- save as BMP (gdImageWBMP)

See the respective manual pages, there is code snippet in each of them
(http://www.libgd.org/Documentation).

Feel free to ask again if you need more details,
