Pham, I have sometimes taken the approach of doing a "gdalwarp to VRT" which creates the configuration of the target dataset in VRT format, but does not actually resample any imagery. The you can open the VRT and query it's configuration. There are also lower level apis to get this information but they are not normally exposed through SWIG in Java, Python, etc as far as I know.
