On the climbout on the SID; Center cleared us direct JOGEN when able. I had been deviating around weather at the time. The First Officer was very new and was having problems understanding the clearance; so I read it back to Center as I entered what I thought was JOGEN on line one on the LEGS page of the CDU. Without realizing it I actually entered the fix after JOGEN and selected to line one and executed. This fix's name; (though I don't remember it now) also starts with J and is very close to JOGEN. In fact there are several points on that SID that start with J. After about five minutes; Center asked us where we were going direct to. I admitted to him I had entered the wrong fix and we would now proceed direct JOGEN. All he said was 'Roger.'
On climbout; ATC gave us direct to JOGEN while climbing through 10;000 feet. Captain had to maneuver to avoid weather for approximately one minute. After maneuvering for weather; the Captain accidentally selected JUNEJ instead of JOGEN in the FMC (due to similar spelling). After ATC queried; we realized the error and selected the correct waypoint.
B737 flight crew reported of confusing intersection names. Captain accidently entered the wrong fix into the CDU and the aircraft was off course.  ATC questioned the crew and they corrected the intersection.
