Try it and see. I can't imagine the keywords for "gcc" would be very high. (especially something open source, and very niche). Other thoughts, rather than adwords, would be to create banners and place them on niche specific blogs for cheap $50/mo, and that could drive traffic too. Also, you could try cold emails or calls from job ads, etc. This is 1% of the pie of ways you can drive business.
