This is PhasePictor, a program for displaying phaseplane of an ODE
(ordinary differential equation).

It was written by Kristóf Kály-Kullai (kakukri at freemail dot com),
the Windows port was done by László Roszol (roszoll at gmail dot com).

To use it you need to have GTK version 2.8 or later and libglade 2,
for printing support you need at least GTK version 2.10.
