  To design a Radio Frequency Quadrupole (RFQ) is a onerous job which requires
a good understanding of all the main parameters and the relevant calculations.
Up to the present there are only a few software packages performing this task
in a reliable way. These legacy software, though proven in time, could benefit
from the modern software development tools like Object Oriented (OO)
programming. In this note, a new RFQ design software, DEMIRCI is introduced. It
is written entirely from scratch using C++ and based on CERN's OO ROOT library.
It has a friendly graphical user interface and also a command line interface
for batch calculations. It can also interact by file exchange with similar
software in the field. After presenting the generic properties of DEMIRCI, its
compatibility with similar software packages is discussed based on the results
from the reference design parameters of SPP (SNRTC Project Prometheus), a
demonstration accelerator at Ankara, Turkey.
