In this post I would like to show how to create a basic webpart in sharepoint server 2007 using VS-2005
Step1. create a visual studio class library project and name it as BasicWebpart as shown below

Step2: rename class1.cs in solution explorer to myWebPart.cs

Step3: Add following references microsoft.sharepoint.dll (which will be available at "C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\ISAPI") and system.web.dll by clicking reference tab in solution explorer. Import two dll's in the class file by "using" like below
using Microsoft.SharePoint;
using System.Web;

step4: inherit webpart class of "Microsoft.SharePoint.dll" with class file as shwon below

public class myWebPart : Microsoft.SharePoint.WebPartPages.WebPart

step5: override render method which is inherited from System.Web.UI.Control to put render some sample text. sample method to render the text
protected override void Render(System.Web.UI.HmlTextWriter writer)
{
writer.Write("This is my First basic Web Part");
}

final myWebPart.cs class file code will be as shown below

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SharePoint;
using System.Web;
namespace basicWebpart
{

public class myWebPart : Microsoft.SharePoint.WebPartPages.WebPart
{
protected override void Render(System.Web.UI.HtmlTextWriter writer)

}
}

}
step6: compile the project with successful compilation.

and under SafeControls tag add the below tag to reflect our new webpart in sharepoint site.

step8: copy the dll which will be resulted from step 6 to bin directory of the sitecollection.

OS Drive\Inetpub\wwwroot\wss\VirtualDirectories\bin"
