Yes unless u need to do something more demanding or feel like implementing a more complex interface, i thing just using the arduino is actually a nice was to go 
My initial idea actually was to make an iPhone app to control everything, but then i just went for the 1-size-fits-all html interface... May be a bit simpler, but it works everywhere 
As i mentioned there are still a few things i want to sort out in the code before making it public, but hopefully it will be done within a month or so
