Does anyone know of some code or tutorial that will teach me how to generate a gif image without using GD?

Thanks!

Can you possibly use a PNG file instead of a GIF?

Unfortunately no... Is there another way?

we can generate one frame image but how to make many frame images ...

there are other api that support gifs, e.g. http://pecl.php.net/package/imagick and from the imagemagick site:
Note that since Unisys claims a patent on the LZW algorithm (expiring world-wide as of June 2004) used by GIF, ImageMagick binary distributions do not include support for the LZW algorithm so GIF files are written uncompressed. Users are recommended to use the PNG or JPEG formats instead, and should consult the Unisys LZW web page before enabling LZW support.
that's better than nothing, isn't it? ;)

If you refer to GD: yes, gif write support is disabled in recent versions,
but imagemagick != gd
