Yup! (btw, I don't mind if you ask me questions about Photoshop. :))
1) Type your text in whatever color
2) Layer>Layer Style>Stroke
3) Adjust stroke to how big you want it
4) Go to Color Overlay and change the font to white
You can ALSO type your text in white and give it a stroke... but if you have a white background it's hard to see.
