For some people it will be quite difficult, and others can make a quality, well-made and attractive table on their first outing. It depends on how well you can work with your hands, what tools or means to acquire them you have, and how much time you're willing to commit.
I spent about 30 hours making my first table. It came out great and has held up well. It was used weekly for about a year and every other year for the past two years. I did a lot of research and ended up spending more on tools than on supplies to make the table itself.
I definitely encourage you to try it. It's a lot of fun and you will have years worth of bragging rights.
