My question has not been answered yet. Do anyone knows the answer? I would like to use the QT-code if it is like I assume.
Did I get it right that the maximum coin amount is 10 million?
Is the coin based on Ethereum source code? If so, then the wallet could be easily transformed to a first Ethereum wallet!?!

Please check OP thread and read it more carefully, i think everything is in there that you'r asking.
No, it is not. I would not ask otherwise. I read the OP carefully but there is no information in the OP if the GUI source code is compatible with Ethereum's source code.
By the way, it is not a good sign when the opening poster is not active this much here.
