insert delete update options in c#.net and sql server 2008

Question

hi..

I had done with an application which is hosted in main server, 

but the problem is when I want to select/insert/update/delete some data in my table I need to connect to the server every time which is not possible for me..

Thats why I am trying to solve the problem by making a page which is having a text area  and submit button.

when I enter the query(select/insert/update/delete) in the text area, and click on submit button, the query to be executed and it should return the o/p to a panel.

I dont know exactly whether its possible or not,

but I think its the only solution for my problem.

if possible can anybody help me to solve this problem...

Thanks in advance,

Raji
