What has that actually got to do with anything? Are you trying to state that it is easy to make an GUI? Yeah sure when someone else already designed the Bitcoin one and most coins just go with making some adjustments and changing the icons.
If it is that easy then go do it yourself.
This thread is just another FUD attempt it seems.
