The government does make it RELATIVELY painless to sign up (well, other than that paying for it thing). You can go to the site by Googling:
Medicare part d signup
Or, just go to this site to find plan comparisons.
Once there, your access to plans is partly determined by your location, so the first step is to enter your zip code.
You will be asked a few questions (I Don't Know is an acceptable answer).
This takes you to a page where you can enter your on-going medications (if this isn't something you need, you can skip it, but if you take regular meds, it will make a difference to the cost of the plans).
You will want to enter your standard medications on the list (easy-peasy), then select one of the 3 options (the first one is for buying Part D separately from your Part B, which your person signing you up should have told you if you needed this). Check the first box and compare plans.
NOTE: pay attention not just to the monthly cost, but to the overall yearly cost - that last one will take into account the cost of your meds (which is why I suggest you enter all the meds you regularly take)
