The first wallet is going to be based on the cryptonote reference wallet, so it looks just like good old Bitcoin-Qt (which cryptonote forked to develop it). I'm not going to say it is sexy, but it gets the job done.

Later we can consider other prettier wallets (Monero has one that includes just dhe UI code and requires integration, for example) and especially mobile wallet, but that's down the road.
