You want a narrow depth of field image. This is done by using the largest aperture on your lens (smallest f-stop number). To do this on a D40, or any dSLR camera, use aperture priority or manual mode and dial in the smallest f-stop your lens has.
The distance ratio between the background you want to blur and the object of interest should be as large as possible.
Also, using a longer lens (highest zoom setting) will give you a narrower depth of field.
Experiment with the above settings to see what it does.
You can also have a blurry foreground with your in-focus subject behind your foreground.
Bokeh gets smoother as your focal point gets further away from your background and your aperture gets wider.
So get your subject farther away from your background and use a faster lens like a 50mm f/1.8
