I don't know how important the choice of language is, but here's a little Perl 
program that does just that:


my $bytes = unpack("H*", join("", (<ARGV>)));
$bytes =~ s/(..)/0x$1, /g;
$bytes =~ s/(.{1,72})/    $1\n/g;
print "const uint8_t PROGMEM myArray[] = {\n$bytes};\n";



And here's its output when run on itself:

$ perl hexdump.pl  hexdump.pl
const uint8_t PROGMEM myArray[] = {
    0x6d, 0x79, 0x20, 0x24, 0x62, 0x79, 0x74, 0x65, 0x73, 0x20, 0x3d, 0x20,
