This gui is implemented in a chip. I can´t find any free software for gui development.

Dani, you can implement RTOS in a pic18F. ucos II can be ported to a pic. Remember that yo can use new pic24. These are 16 bits microcontrollers with DMA, up to 40 MIPS (PIC24H). You only need port ucos II to this microcontroller and use ucgui. You can use Atmel ATMEGA series too. These are 8 bits fast microcontrollers (up to 16 MIPS).
