You are not likely to be successful writing a disk on a mac to be read on
the pc.  Instead you want to be looking at programs which allow you to
connect the serial ports or somesuch of the two machines and use a kind of
file transfer technique.  Numerous means exist to do this and your choice
will depend a lot on how frequently you need to do it, the amount of money
you can apply (eg TOPS can connect the two together), and on your tolerance
for what at first might seem like complicated series of actions to perform.
If you can put up with the latter you might want to look into Kermit which
can be used for this purpose.  The Mac telecommunications program Red Ryder
has a workable implementation of Kermit on that side.

Whether you escape this with your sanity, and whether many of us who may want
to do the same thing if you are successful, depends almost solely on whether
the provider of WordPerfect for both machines has provided the means to 
write the files in such a way that they can support this kind of transfer.
If they did not it would in my mind be reason enough to disdain the product
on either platform.
