Need Assitance in creating a simple Cocoa OS X application

[lilabila]

Dear readers,

I hope you can help me a little in getting done a simple application.

System requirements:
10.6.8+
32/64bit Intel
MacPro1,1 / Dual-Core Intel Xeon + Higher

My Computer for programming this is an 2011 MBA, latest X-Code, 10.8.0

The program should do the following:

2 text boxes
box 1 (enter link for picture)
box 2 (enter text)

submit button
replaces the characters from box1 & box 2 to the corresponding placeholders in a static html template
During this process the program checks the characters entered in the boxes for HTML-TEXT compatibility
At best it will convert the bad characters automatically
Then it will perform an XHTML validation check

Pop-Up-Window
Opens with the html source code for selecting all and copying it to the clipboard (without editing functionality)
By default it will copy the altered source code to the clipboard anyway
On top of the window it states that the new source code has been created succesfully and one can paste it to the desired location


Because I'm very new to X-Code I'm having some difficulties in telling the app how to write the parameters in template, and how to work with the HTML checkings I desire

I appreciate any help!

Sounds very much like homework.

If it's not homework, tell your boss to at least get you some decent Cocoa programming books and some time to learn.

Hahaha, yes it does! I want to write it and I'm trying to get into Xcode with this thing, at least I hoped to get some hints because it's driving me mad that I don't get it! Like stated above, writing into a specific place into a file...

Calculators and Faders I can already create by now

Anyway thanks for the comment it made me laugh!
