I was trying to install some new fancy fonts in GIMP2. After installed the font in windows system, GIMPS was having trouble to load the fonts. However, MS Word is able to see it.
After digging around the web, the follow solution helps me solve the issue:

In GIMP2:

click on “folders”
click on fonts. you should see a line that points to where the fonts are
click on the icon that looks link a piece of paper
browse for the directory where the fonts are and add it to the list
