Very new to components

I am interested in creating a component for an existing calendar application I have created. As I'm sure you noticed by the subject I am very new to components so I will probably ask a lot of (probably less intelligent) questions. Please forgive me when that happens.

I used VB back in the days of 5 and that was only for a few months so we might as well assume I am a beginner.

So far I understand I am supposed to have a project called something related to the action it will be doing (calendar) and a class related to it as well? Is that right?

calendar.ViewCalendar

I have created a basic on that did a .Write command directly in the VB which gave me a beautiful "Hello World". Obviously not everything will contain Response.Write commands, how would I convert my coding?

Thanks for any help.
