Sample webpart in VB .NET

I would like to have coded two sample webparts for Microsoft Sharepoint Portal Server 2003 accessing my SQL Server and mySQL databases. They should be coded in Microsoft Visual Basic .NET 2002, which is the version we have. Imagine I have the following table in my database (this sample is taken from my mySQL database). CREATE TABLE `oz_gasto` ( `id` int(9) NOT NULL auto_increment, `fecha` date NOT NULL default '0000-00-00', `id_oz_contacto` int(9) NOT NULL default '0', `id_oz_proyecto` int(9) NOT NULL default '0', `id_oz_tipogasto` int(9) NOT NULL default '0', `importe` float default NULL, `justificante` char(1) NOT NULL default '', `visa` char(1) NOT NULL default '', `descripcion` varchar(255) NOT NULL default '', `id_oz_diapago` int(9) NOT NULL default '0', PRIMARY KEY (`id`) ) I would like to have a webpart with the following controls: - A text field where I can write down a query, for instance "select * from oz_gasto". - A button to execute the query - A grid control to show the results I am interested in using the same code for both SQL server and mySQL databases, if possible. So all the code to manage the database must be encapsulated in an object. Since I have never worked with webparts, I would like to receive detailed documentation on how to add the new webpart to the sharepoint portal server, and on how to install and configure it. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
