I have a jack with 4 data ports and I need to make one of them an analog for a fax machine. Is this a hard change to make? I'm kind of a noob so any help is greatly appreciated.

All you have to do is make a cable using pins 4 and 5 that connects to the punch down blocks for the analog line and plug it into the patch panel for that cable.
Or have a 25 pair cable installed with a pair punched on the white/blue of each patch panel port and the other end on a block at the MDF/IDF and cross connect the analog line to one of the pairs and patch through to the port going to the jack.

A little technician's insight- That's the beauty of the TIA/EIA 568 design. Feed your lines to a patch panel, and use standard patch cords to feed them to standard jack locations. User friendly.
However, if your infrastructure has been comprimised by a contractor that believes in "2 pair per network connection", splitting pairs off one cable to provide another connection, you may need a technician to sort it out.
As a rule, if you've got 4 pair (8 wires)punched down on the back of your patch panel, you'll be ok just plugging the fax line into whichever jack corresponds to the patch panel.
If there are only 2 pair (4 wires) connected to the back of each port on your panel, fire your cabling guy, and hire a real technician to fix his work.

This is something that is done fairly often.
All you have to do is use patch cord with solid wires from the panel port that you want to become hot for the analog line to the connection block for your analog lines.
At that end connect the white/blue and the blue/white pairs to your analog line location.
You may want to custom make this connection cord from either cat5 or cat3 cable,so that you will have a closer correct length from one connection to the other.
Good Luck,
