You can use a perl script to extract the tables from 
draft-ietf-idn-nameprep. They're in machine-readable format. That's 
also what TT does for generating the Unicode tables for QString.

You can adapt the source code from draft-ietf-idn-punycode-nn.txt. It's 
already in C (this is from an old version):

enum punycode_status punycode_encode(
  punycode_uint input_length,
  const punycode_uint input[],
  const unsigned char case_flags[],
  punycode_uint *output_length,
  char output[] );

    /* punycode_encode() converts Unicode to Punycode.  The input     */
    /* is represented as an array of Unicode code points (not code    */
    /* units; surrogate pairs are not allowed), and the output        */
    /* will be represented as an array of ASCII code points.  The     */

enum punycode_status punycode_decode(
  punycode_uint input_length,
  const char input[],
  punycode_uint *output_length,
  punycode_uint output[],
  unsigned char case_flags[] );

    /* punycode_decode() converts Punycode to Unicode.  The input is  */
    /* represented as an array of ASCII code points, and the output   */
    /* will be represented as an array of Unicode code points.  The   */
