It's not a big deal. All you need is just HLL implementation (e.g.
C/Pascal/whatever w/o ASM whatsoever) and draw the stuff in an off-screen
buffer. This is the most general way to keep the thing extremely portable.
Basically, this is what people do when they start software rendering for a
very 1st time, they just implement everything in HLL, test the stuff, debug
it, find fastest algorithms and the hardware dependent part is flipping the
off-screen buffer to the screen. If the proformance is not aceptable, some
hardware dependant approaches come in play (like ASM).
I have my own tmapper in C that does that for 8bpp modes and it's not anyhow
complicated, though if you're going to add light and other sophisticated
stuff on top of it, it will be.
