   Cool!  what kind of performance to you get with the LCD?  I imagine it needs a really high SPI rate and maybe DMA to be fully satisfactory.
   
   NX is a windowing system.  NxWidgets is the companion library for buttons and the like.  LVGL is a non-windowed option.  LVGL should have lower resource usage and probably better performance since less clipping involved.
   
   Another option option is pdcurses.  Ken Pettit did some great displays (and even added logic to remote the curses display.  You would have to use a NxTerm for pdcurses.
