1) Select Geometry->Elementary->Add->New->Point
2) Enter the coordinates in the dialog box and press "Add"
3) Repeat with different coordinates
4) Select "Straight Line" (the button below "Point" in the
   Geometry->Elementary->Add->New menu)
5) Select the start and end points in the graphic window
6) That's it: you've just created your first line :-)

It's exactly the same for surfaces (you select the bounding lines) and
volumes (you select the bounding surfaces). Always have a look at the
messages in the bottom right part of the graphic window: they tell you
in which state the program is, if you need to select an entity, etc.
