I have long experience with 8-bit and 32-bit micro-controllers. I work with PIC , AVR , ST
and NXP micro-controllers. I use KEIL IDE , Atmel Studio and MPLABX IDE .
Regarding your project , I would use any AVR chip u want ( I can propose one) or arduino board.
I would be able to develop ur GUI through alphanumeric or Graphical LCD .
I deliver tested , neat and well-commented code that can be reused or modified for future development.
More to be discussed once you contact me .
BR,
