I recommend buying a nRF51 DK if you're new to Nordic. The nRF51 DK has a On-Board JLink programmer so you only need to connect it to your computer via USB in order to program it. You can also use the nRF51 DK to program external nRF51/52s, e.g. custom boards or third-party modules for for prototyping. As Nguyen Hoan Hoang already has mentioned you have to use Keil or Eclipse+GCC or Segger Embedded Studio in order write and compile code for the nRF51.

Yep, there are lots of learning to do. Keil is a $5K license. It is free only for 32KB of code. Eclipse is OpenSource totally free development environment without limits.

Seems there is a lot of work for me. So if i understand correctly i nned to buy NRF51288 DK motherboard, and using it upload hex file and then start programming a board? Is devzone.nordicsemi.com/.../ tutorial covering everything for me?

I see that there is keil used - i couldnt download it yet but is it free? Will eclipse do same thing?

The nRF5x chip does not have a default bootloader. You need to use a debug jtag such as the Segger Jlink or the IDAP-Link to program the device. You will also need the Nordic SDK for development. The programming is more advanced than Arduino. You can use Eclipse & GCC as development environment. It's a steep learning curve. I hope the links help you to get more insights.
