It's common to need a feature like this but the solutions vary depending on the environment in which the image will be used. To my knowledge there are no off-the-shelf GIMP plugins/filters that provide the functionality you're requesting. That doesn't mean one doesn't exist.

Yes, if you're familiar with one of the programming languages supported for GIMP Plugins (C, Python, Script-Fu by default - there may be others). You'll need to become familiar with the plugin API. In 2.6, look under the Help menu for "Procedure Browser". The way you use these is dependent on the language you choose. If you intend to use these images on the web you might be better off using dynamic support for this feature, such as what you see with NextGen Gallery, a plugin for Wordpress (blogging software for the web). On the web you can use code to overlay text onto graphics without actually modifying the image itself. In this way you can edit the text displayed without having update the image. For an example of how this works you can view my Dept 56 Galleries: http://www.graphics-muse.org/wp/?page_id=119 (view these with the PicLens option to see the overlaid text in the upper right corner of each image). Another option is to use an image management tool like f-Spot or similar. Many of these offer builtin options to do exactly what you're asking, though they may not be as flexible in how they composite the text onto the image as you require. However, if you really do need to update the image itself and you want to program it yourself, you might find it easier to automate this with ImageMagick. The advantage to this option is that it's more scripted from the shell and doesn't require running a UI interface. GIMP can (I believe - I never use it this way) be run without the UI but I'm not sure it's particularly easier to script in this way. That said, you'll get excellent results using the GIMP's plugin API. You'll end up writing a file browser of some kind to select files, specify the input CSV file and then have the plugin open, edit and save the files all without actually displaying them (to save time).
