Tkinter can do all that.  A few suggestions:

- You will want to use a Text widget for your main display.
   Conceptually, this widget displays a sequence of lines of text.
   An image is treated as a single character: it is displayed on a
   line between the text that comes before it and the text that
   comes after it.

- Use tags to change the appearance of links so the reader will
   know they are clickable.  You can apply named tags to any
   number of regions in your Text widget.  Each tag is associated
   with options such as text color, background color, and font.

Here's a Tkinter reference that may help you:

Read closely the sections of "The Text Widget", especially
the subsections "Text widget tags" and "Methods on Text
widgets".  In the latter subsection, note these methods:

.tag_add:  For applying a specific tag to a region of text.
.tag_bind:  Make regions tagged with a certain tag respond to
             events such as mouse clicks.
.tag_config:  Change the appearance of all regions tagged
               with a certain tag.
