You can easily use FrontPage 2003 and create a WebPart based on
DataView (See Data Source Catalogs and Data View Details located in
the Task Pane)

By using this mechanism, you can connect to databases (using OLEDB),
XML files and WebServices.

I hope this is an excellent starting point!

I want to show info present in a csv file any ideas how to do this.

The following is a generated ConnectionString that ADO.Net
understands.
Note that by default you can connect to a SQLServer database, but if
you know the proper connection string, you will be connecting to any
database.
In this case, the database is a folder that contains the tables with
*.csv or *.txt extensions.

Provider=MSDASQL.1;Persist Security Info=False;Extended
Properties="DBQ=C:\Path\To\Your\CSV\Repository;DefaultDir=C:\Path\To\
Your\CSV\Repository;Driver={Microsoft Text Driver (*.txt;
*.csv)};DriverId=27;FIL=text;FILEDSN=C:\Program Files\Common
Files\ODBC\Data
Sources\CSV_Text.dsn;MaxBufferSize=2048;MaxScanRows=8;PageTimeout=5;S
afeTransactions=0;Threads=3;UID=admin;UserCommitSync=Yes;"

You must create the proper DSN file using the ODBC wizard, selecting
the proper driver (Microsoft Text Driver) and replace the
path "C:\Path\To\Your\CSV\Repository" with the proper location.

I hope that this is going to work...
