+We are totally agree with the reviewer, that it is a good idea to provide a GUI. However, adding GUI is a very time consuming task and we do not have any funding for this.  Actually, the code described in our previous publication has no GUI either, still that paper has more than 50 citations. So we should expect that this code and the manuscript are valuable and important even without GUI. In our first comment in this reply we have tried to cover the cases, when Mathematica usage is not beneficial.
