First: I'm not a professional. I just want to know what is possible and if i'm on the right track.
Second: I want a little microcontroller which just measures (for example) the temperature and send it to my server (can send/receive bluetooth). It should be a SoC. I googled a lot and found an ARM Cortex M0 at nordic semiconductor which has built-in bluetooth (2,60 $) which I want to use. Before I continue and look for a professional to help me I want to ask you …
The question:
Is it possible to put this ARM cortex M0 with built-in bluetooth on a little board with some pins and connect it to a small power source? Would this work, or would I need a lot of components (resistors to pins, capacitors etc.) on that board?
The solution should be as simple as possible to keep it small.
I also googled for existing solutions, but they where 10 times more expensive than a simple ARM Cortex M0 would cost. I found a little iBeacon/Beacon which would cost 4$ with an ARM Cortex M0 and also some pins to connect some sensors, but it was to large (lot of capacitors, resistors, …).

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.
