How I can groupcoin wallet:
1) download Pankkake's ova-file.
2) import this file into VM,
3) start VM with login\pass groupcoin,
4) wait while groupcoind synchronized data (approximately 2 hours),
5) some intresting command (Pankkake gives me):
    groupcoind help
    groupcoind getinfo
    groupcoind getnewaddress
    groupcoind sendtoaddress
    groupcoind listtransactions & etc.
Now I have groupcoin address - 2hh8R3QHsDmcsbAGZyVG49FGrERb1S78m4d
Question: how I can build GUI-wallet with my new groupcoin address? Example - bitcoin & others cryptomoney.
I see screenshot in this theme from RoadTrain, but I did not understand how to do it.
Explained to me please step by step.
