GIMP :: Editing Multiple Text Boxes?

I want to do a glow effect on a logo that I am working on.. the problem is that all the tutorials I've seen are for single text boxes. I will need to have different sizes and fonts so it requires more than one text box. I can edit the first text box to where I can "path from text," add a new layer, "select from path," create an outline using the "grow" effect and then blur the it so it looks like a soft edge with a different color than the text. I would like to do this for each text box, but when I add a new layer for a new letter and attempt to "select from path" it will only highlight the letter that I've already completed with the glow effect. I'm thinking I will have to save the file each time I create a new glow letter and reopen as a new file to add one more glow letter... but is there a faster way? I've attached a screen shot... the whole logo will read like this:

The A,W, and G will be larger and in a different font than the lowercase letters when its done. SO I will have 6 text boxes total.
