Thanks Groxar, if you wanted to share your technique that would be brilliant. I am very new to the world of glsl shaders, and would love to learn more.
1. have the thing you want to make glow in white (in my case some text), I have a black background layer so I can see what happens each step (you can delete the black background layer at the end)
2. Duplicate the layer with your thing and apply the Gaussian Blur effect on it (in the image I chose a strength of 25)
3. Duplicate the layer with the blurred result a few times (in my case 3) and combine the layers
4. To be able to change the colors of the glow and text (or whatever you made glow) save each layer separately (saving your image like this in paint.net defeats the purpose but the next image is what you could achieve by just changing the SpriteBatch color :3

That's really great, thanks for taking the time to do this Groxar. I will give it a go.
