The quick and dirty way is to make your text several times in outline color, shifted by small amounts in a circle around the text position:
one
8 | 2
\ | | /
\ | /
7 ---- * ---- 3
/ | \
/ | \
6 | 4
5
Edit : Doh you were faster! I will not delete my answer, although this ASCII art is simply too good and deserves to live!
Edit 2: As mentioned in OregonGhost, you may need more or fewer steps to render outlines, depending on the outline's width.
