You can use QCA to do this. Install qca and the qca-ossl plugin (and openssl 
of course). Once you have verified this works take a look at the examples and 
you will find one called rsatest which shows you exactly how to do this. A 
link to this example is:

The basic steps are these:

QCA::PrivateKey seckey = QCA::KeyGenerator().createRSA(1024);
QCA::PublicKey pubkey = seckey.toPublicKey();

HTH,
