Arduino Due with ATSAM3X8E program with Arduino software

Hi,

how can I program the Arduino Due with ATSAM3X8E with the Arduino software?
I`m able to choose the correct com-port and I can choose the Arduino Duemilanove or Diecimilia board. But there is not the correct processor listet. Is there another software which with I can program the arduino due easily, without using C?
At http://blog.atmel.com/2014/03/29/a-closer-look-at-the-atmel-powered-arduino-due/
they say:
The Arduino Due can be programmed with the Arduino software.
Can you help me?
I do not want to program in C.

I am presuming that you are using the latest IDE. To program the Due you will need to download the necessary packages for it through the IDE's Board manager.

This can be done by selecting from the menu: Tools --> Board --> Boards Manager. Once the board manager has been launched you can then select and install package to support Arduino SAM boards.
