Is this going to be a huge If/Then statement?

I am trying to implement a series of notifications based on radio button options the user selects. The notifications date and time will set depending on both radio button options and the user selected date.

for example the user selects Option 1, 2 and 3 along with Jan 1st 2017 and 12 notifications are set every couple of days/weeks depending on said options.

Before I get too far into this, am I just looking at a complex if then statement to set these notifications or am i missing another solution?
