Simulating multiple components with MPLAB

[newtekuser]

Can MPLAB simulate a complete project, or just one component at a time? I.e.: my project consists of a PIC16 MCU driving a 16x2 LCD and a few buttons with which the menu is controlled on the LCD. I'd like to be able to simulate inputs from the buttons and see the menu output in the console.

Standard MPLABX only simulates Microchip's devices. There is MPLAB Mindi for analogue simulation but I've never used it.
Labcenter's Proteus can do it, but that's a paid for program.
