Tim whilst others, and indeed the OP, might appreciate your humour I suggest it's a little out of place in response to a genuine request by a comparative novice! Would have been better if you had finished it with a smiley
To Kay I endorse the suggestions for the Miner's or PYG Tracks, and possibly Snowden Ranger (which as has been said) you might find a little but not massively exposed at the top.
I recommend you avoid the Watkin Path which is very steep and on loose scree for the last bit, and obviously the Horseshoe via Crib Goch which involves a very exposed scramble. Both of these ways are great, but definitely not for a solo novice until you know how you cope with exposure*
As has been said, take waterproofs and warm clothing. It can get cold up there, particularly if it's windy. And a map and compass which you should know how to use in case it clouds over.
* By exposure I mean ground with a big scary drop under you!
