As above, more information would help.
Have you started anything yet? If so, what have you done, and where are you doing wrong?

Also, there are many sites that have tutorials on how to make an interface(I'm assuming you mean a GUI?)
Start by looking at those sites, and just make the GUI. After that, read up on how to make those buttons you put on the GUI work.
I had the same problem as you - I didn't know where to start.
Bottom line: Google is your friend

what i dont know how to do and the forums kinda confusing me is this.
I want to be able to create a txt to serve as my database then call that txt that has all the information to use in the login pane so that i can verify the username and password part... another group memeber is doing the login thing
P00dle 0 Junior Poster
Do you have to use a .txt file? In my experience(I don't have that much though ^^), using SQL or even MS Access is so much easier.

If you want to use a .txt file, and you find databases difficult find examples on how to read files in this forum using the Scanner class or the BufferedReader class.
After you read the file into a Vector or ArrayList check the username and password entered to see if they exist in the data read from the file.
For databases and how to login, check the jsp forum. There is an example on top called MVC. You can read and take the database and validation part.
