I have something that I use to create simple buttons. I use the command line
interface version of php to create the buttons offline. However, the
function can also be used on an web application easily.
I am creating the image with fixed height and width, you can change it by
using $i_width and $i_height variables in call to ImageCreate /
ImageRectangle/ImageFtText function.
Change it as you like. One thing, is the fontfile has to be an absolute
file path.

$pointsize = 15;
$fontfile = "/usr/local/fonts/arial.ttf";
$imagefile=$name.".png";
$string_size = ImageFtBbox($pointsize, 0, $fontfile, $string,
array("linespacing" => 1));
$s_width = $string_size[4];
$s_height = $string_size[5];
$i_width = $s_width+2;
$i_height = -1 * $s_height+2;
$im = imagecreate(115, 22);
$white = imagecolorallocate ($im, 255, 255, 255);
$black = imagecolorallocate ($im, 0,0 ,0);
ImageRectangle ( $im, 0,0, 114, 21,$black);
ImageFtText($im, $pointsize, 0, (122 - $s_width)/2 - 1, 22-(22+$s_height)/2,
$black, $fontfile, $string, array("linespacing" => 1));
ImagePNG ($im,$imagefile);
ImageDestroy ($im);
