You guys are working on a freaking GUI and database wallet for ages now suckers!!!
Almost as long as eduffield's been working on Masternode blinding!
Not sure if you are for real or not, but GUI wallet is a basic job for a crypto currency programmer.
depends on the quality of the GUI and how long you want the GUI to last.... because if you make a GUI to work with the current version of the interworkings and you know you are going to change the interworkings soon then you'll just have to remake the whole GUI
