Of course you have plenty of out-of-the-box web parts, or just by going to Codeplex you will be able to find tons, but you never knows what your organization is going to need.
Because of this I have decided to create a sophisticated web part, that gets the weather from a web service and post it into a textbox. This web part includes events, so we will be able how to interact with events and web parts.
The easiest way to create a from is by using our new classes coming from System.Web.UI.WebControls,
I am going to list all of them so you know what you can do after this tutorial:
1- Create an Empty Sharepoint project, select where you want to debug your project and select "deploy as farm solution". Type the name WeatherWebpart as name of the project.
2- Go to your project Right-Click add new Item and select "Web part" (DO NOT CLICK ON VISUAL WEB PART).

3- Call this new Web part "GlobalWeatherWebPart".
4- Go to your project, right-click, add service reference->advanced->Add web Reference... (on the bottom) and paste this address: http://ws.cdyne.com/WeatherWS/Weather.asmx?wsdl
5- Call the wen reference WSWeather.
6- On the project menu, right click .
7- On "GlobalWeatherWebPart.cs" copy and paste the following code and deploy it, now you can go to your web->Site Actions->New Page->Insert Ribbon->Web Part->Categories->Custom->Select "GlobalWeatherWebPart"->Add->Format Text->Save and Close:

Conclusion
Visual Studio will allow you to create anything with Web Parts but be aware you have what we call "Visual Web Parts", where you can design the forms in a ASP.NET way... in 5 minutes...
