Depending on how familiar you are with programming in pari library mode, it might be easier to start with a GP script, and potentially use gp2c to transform it into C code using libpari. Or simply stay with GP... Otherwise, did you work through the "User's guide to the pari library" available at http://pari.math.u-bordeaux.fr/doc.html ? In particular, Section 8.3.1 explains how to create a vector of coefficients, which can be used to initialise a curve as explained in Section 13.1.1. Andreas
