GUI Version of sendmany

[vv01f]

I wonder if there is a nice solution for trading/withdraw BTC miltiply.
The last week I started mining with very low-end hardware. Instead of buying some rig and invest money in hardware I decided the trade with BTC might be a better solution for me.
So now I end up sending them manually or via some traders.

So now I thougt there might be a nice front-end for sendmany. Any advice?
