For what you need it doesn't sound like you need a full fledged X system. Not comfortable with command prompt isn't a good reason to install X system in my opinion. Basic commands potentially you can figure out.
What's wrong with a text editor like vim?

You can scroll, by default not with mouse, but you can enable mouse pointer as well via .vimrc configuration file. Assuming system supports mouse or it is configured for that.
You could scroll with vim much quicker than you'd do with a mouse, that I can assure you, because you could jump to a particular line with couple of key strokes.
If file(s) you are going to navigate through are big, I'd even recommend to get such text based editor, because it is much lighter on system resources than editor with more sophisticated graphical user interface would be.
