Okay, I'm biting the bullet and deciding to get into the whole Microsoft/C#/.NET culture and I'm going to do this by putting together a simple (hah!) application.

It will basically be an application in which I want to store images and associate with them other optional things.

It must be able to import images from the filesystem (and hopefully camera/scanner) then allow the user to add text, audio and other information.

I plan to store the images and auxillary information into a database. What the application will do with said data isn't important (yet).

Keep in mind I know absolutely nothing about C# or .NET although, as an old codger, I know a great deal about many other things and will regale you with stories and anecdotes until you quietly slip away :-)

What are the first steps to take in developing such an application? I've already set out UI layouts and likely process flows although it may be that the development environment dictates changes.

Development environment is currently XP SP3 + VS2008 (though I can upgrade if absolutely necessary).

What should I be looking at as the first step? Are there any gotchas I should be looking out for?
