Appointment Reminder Program

I want a program that can use a table of information and send a SMS text message using email to a person's phone to remind them of the date and time of their next appointment. I want to run it on a Windows machine. I want to be able to use a table containing CLIENTNAME, CLIENTSMSEMAILTOPHONE, DATEOFAPPOINTMENT, DAYOFAPPOINTMENT, TIMEOFAPPOINTMENT, LOCATION, APPOINTMENTWITH(Name), CONTACTNUMBER, NOTIFYONEWEEKPRIOR (Yes/No), NOTIFYONEDAYPRIOR(Yes/No). Program should run in the background, query table, and conduct notifications as scheduled. Notification message should be editable and initially should read "CLIENTNAME has an appointment with APPOINTMENTWITH on DAYOFAPPOINTMENT, DATEOFAPPOINTMENT at TIMEOFAPPOINTMENT at LOCATION. Please call CONTACTNUMBER to reschedule or cancel."
