Dear Kalami,

Of course, you can do that in QE (pscf), but applying strains and calculating total energies for these strained lattices.
There is no direct way to calculate elastic constants in QE (I mean prepare an input file and submit a job). 
Please find the paper "First principles elastic constants and electronic structure of \alpha-Pt2Si and PtSi, O. Beckstein, J.E. Klepeis, G.L.W. Hart, and O.Pankratov" in Phys.Rev.B or cond-mat in arXiv.org (0008200v2) about strains to be applied.

Please do not forget provide your affiliation.

Bests,
Eyvaz.
