Just make a root rib template and a tip rib template. Stack the correct number of layers of 1/16 balsa for all the ribs. aligned by the SPAR and the zero AOA line. Drill and screw the stack together. Carve a straight transition from the large rip to the small one. You will have a stack of the correct ribs. (assumes the wing has a constant taper angle)

No ned to go through the meathematicl gymnastics... and plotting all the points. Just cut the ribs.

BTW... QuickBasic is a "superset" of Q-Basic. Q-Basic (which shipped with MS Dos 5.0 to Win98 (yes, its there you just have to search for it. qbasic.exe) will run almost any QuickBasic code. The primary difference is QuickBasic has a compiler.

You can also search the net... Q-Basic interpreter is available for DL on a ton of sites. And yes... it will run in WinXP. (so will the compiler.)
