Depending on your skill level these may be helpful or of no consequence.

I wish I had more time to help you get this working.

Ok, it is possible, but the steps depends on your MCU: I've a port for the ST7781 for UTFT. PIC32 are well supported by UTFT, but not all chips, so you've to rewrite the hardware/pic32 items. Currently supported: PIC32MX320F128H, PIC32MX340F512 and PIC32MX795F512 PIC32MX250xx only works currently with SPI mode (no 8-bit data) I've added into the zip (it comes from energia/TI stellaris, but should be 100% compatible) the necessary ST7781 driver, you call it with "SEEEDV10". Please don't ask me about the 8-bit data pinouts, just look inside the /hardware/pic32/youMCU.h file. Beware: there are some chepo 2.4 tft-lcd-whatever out on ali and ebay, they've an ili9340 chipset (but declared as ST7781/St7783)
