There are several different options for creating PDF documents. If you have full version of Adobe Acrobat, simply use this program to create a .PDF from a Word document or something similar. If not, you can use Primo PDF (which is completely free) to create a .PDF from a Word document.

Once Primo PDF or Acrobat is installed, open a document in Microsoft Word, select 'Print' and then under 'Printer Name' select 'Primo PDF' or 'Acrobat.' Now hit the 'OK' button and follow the instructions.

Take note that Primo PDF is not a full-featured PDF document editor. It will simply allow the printing of documents, forms, etc. to PDF format. However, a full version of Adobe Acrobat will let you create PDF's from scratch.
