Once you have the info in your chosen program - I use Family Historian, which is not free, but wich I think is pretty good value, you can get the program to draw family trees which you can then copy and paste into a Word document (or OpenOffice or whatever). Here's a screenshot from Family Historian; the Copy diagram puts the family tree onto the computer's clipboard; then in Word just use Edit>Paste and hey presto! the diagram is in your document.
If you don't like the formatting of the family tree, you'll find the software allows you to make it suit your preferences.
One word of caution - you are using Windows XP which is in computing terms elderly. Do check that any program you try to install will work in XP - the websites will confirm for you.
