How to make a VC++ program web enabled

[Rostrox]

Hello: I have a VC++ 6.0 executable program that only has one screen, such as control panel, it has many buttons and a displayable field. Depending on the buttons pressed, the program reads, validates, generates complex reports of ascii, or access files. Many guys use this program so I installed this in every PC that needs this program. For the other side, I am interested to know about WEB programming and apply the necessary changes to my program so it would not be necessary to distribute it in every PC. However, because I am a novice, I have the next questions: 1. What things should I consider before modification of in my program so it can be WEB enabled? 2. In which moment should I use a complementary WEB programming languaje such as JAVA? 3. Is there a Web site which could help me more with my case? Thank you for your help!
