The product or solution you talk of here is Ghostscript. a GNU program which can read and write out PS and PDF documents.
you can configure it to read a .ps file (easy enough to create ps files.)
and then you conver them to pdf files with something called ps2pdf which is actually a batch file, sending in the name of the ps file and some command line options Ghostscripts converts it to a pdf.
here is a web version if you want to try it out.

My trouble with using this 'free' solution is its not that easy to get all the pieces working together,... and just the thought of having to write a vfp install which installs ghostscript, and so on... gave me a headach.

You might try looking arround on www.pdfzone.com for alt soltuions to your pdf needs.. or if you have newsgroup access there is a good newsgroup which tackles this subject called comp.text.pdf
