minimal ARM (cortex m0) board
It looks very feasible although you will need to mount the chip onto a breakout board yourself and considering it is only offered in a QFN or BGA package, you will probably need hot air rework or some sort of reflow oven.  

QFN to DIP breakout boards are very simple and can readily available on eBay or some electronics store like Sparkfun.

You will need a couple external components.  


It looks like the chip has specific pins to place a decoupling capacitor on (which is really really nice).  
You will probably need a pull-up resistor on the reset pin so your device doesn't reset randomly should you leave it floating.  
And you'll also either need some form of antenna, it could be a trace antenna or a chip antenna, or even a hefty SMA connector for the screw on antennas.
