The trust systems of OpenPGP (web of trust) and X.509 (hierarchical) are not compatible, nor are the signatures (the "math behind" both of them in respect to the keys indeed would be, as long as the algorithms are defined for both, for example with RSA). While you could easily map the hierarchical X.509 trust system to the more powerful (and complex) ...
