I've used lab view on Macs but not on PC's.  Call Labview, they know who 
has developed what you need.  I do speech perception work on a PC and 
use Turtle Beach sound card with their native application - Wave.  
Pretty inexpensive.  I also have Sonic Forge.  Very nice but much more 
expensive.  Generally, if you need simple stimuli - like a sine wave, 
you can generate it off line (say from an audiometer to a tape deck), 
then import it through the sound card and the software, then save it.

If you're really serious about using a PC, use a very fast processor 
(100 MHz or faster), and a hard drive designed for audio-video work.  
You want the fastest transfer rate possible it you digitize at high 
rates.  You also need a large disk drive - audio files take a lot of 
disk space.
