In the latest version of Extension Library you get Bootstrap, jQuery and Glyphicons simply by enabling the bootstrap theme, but If you for some reason can't use ExtLib or the Bootstrap theme I have created an application that is enabled for Bootstrap, jQuery and Font-awesome without using Extension Library.
Font-Awesome and Jquery are not included in Bootstrap but you need jQuery to run Bootstrap. I have added Font-Awesome because it contain many more icons than the glyphicons do.
All code is included within the application and is ready to start using, download link available below
I have only tested this in latest version of Domino (9.0.1) but should work also in 8.5
