Get out Paint.Net
Make the backround Black
Then, make any text you want in White
Then New Layer
Now, in the new layer, paint over in any colors in the white text, so you can't see any of it.
Now make a Gaussian Blur about 50 radius, or just experiment.
Then select the layer, and make the layer, Darkened.
And when your done, your text should look something like this.
And now your done.
