Maybe you can find what you request from referring to CE223726 - PSoC 6 TFT Display Interface with EmWin Graphics Library
Before getting started with the code, please update to the latest version pdl3.0.4 and redirect it to your PSoC Creator P6 project.
I have already tried the demo code available in the link. I am actually referring to EmWin GUI Builder tool which is part of emwin graphics library supporting tools. Using GUI Builder one can build GUI using widgets and pre-defined menus in a graphical way and import the corresponding "c" code into psoc creator project.
I found that the same is possible with microchip micro-controllers(MPLAB installation comes along with EmWin GUI Builder.exe).
