1. one program has to say the smartcard firmware "generate 2 RSA keys for
me!" I think GPG is the one for this job, because you also generate your
with GPG.
2.  GPG has to give the symmetric key (3DES, blowfish etc.) to the smartcard
and get the encrypted symmetric key (encrypted with the public key) back.
then GPG has to compose the whole message with the data- and the key-part.

PGP does support this feature. I found this at the support page of PGP:

Three smart card types have been certified to work with PGP 7.1

    * Rainbow's iKey 20XX
    * Schlumberger's Cryptoflex
    * GemPlus GemSafe Enterprise

For best results, we recommend using these cards. PGP also provides more
generic support for any type of smart card that provides full PKCS#11
