Light advice on a walking programming experience databse

Question

So I've recently finished my C# course and decided its time to take on my own project & looking for some directional advise...

What I was planning on doing is creating my own personal walk around MSDN of whatever 'select' information I'd like to add to it over the next few years...

Each topic such as HTML, CSS, C# and all its topics to be loaded into a Tab form by Head Topic & Tree View by further details.. Selected nodes to display to a split panel with editable code to save changes or code code etc...

The advice I'm looking for is a rough outline of how I should go about this?

Keep it as a windows forms project?
Info to be stored on sql? access? XML? (I'm thinking Access or XML to allow me to move the app around between work and home)

Should I rather make it an ASP.NET project and store everything online?

I imagine that things will eventual start to slow down as the database grows, what would be the fastest means to access the data by the given layout choice?

Hope you guys can help
Peace out
