Can't believe noone has done basic yet!

10 input "Hello!  What is your name?",name$
20 print "Welcome to Ubuntu, "; name$

	{
		System.Console.WriteLine("Hello! What is your name?");
		string name = System.Console.ReadLine();
		System.Console.WriteLine("Hello, {0}! Welcome to Ubuntu!", name);

Objective C (more complicated than it has to be)

#include <Foundation/Foundation.h>
#include <stdio.h>

@interface User : NSObject
{
    char *name;
    char *os;    
}

- (void) setOS: (char *) os;
- (void) setUser: (char *) name;
- (void) welcome;

@end

@implementation User

- (void) setOS: (char *) osys
{
    os = osys;
}

- (void) setUser: (char *) username
{
    name = username;
}

- (void) welcome
{
    printf ("Hello, %s! Welcome to %s\n", name, os);
}

@end

int main ()
{
    User *thedoc;
    char name[100];
    char *os;
    
    printf ("What is your name? ");
    fgets (name, 100, stdin);
    name[strlen(name) - 1] = '\0';
    
    os = "Ubuntu";
    thedoc = [User new];

    [thedoc welcome];

RUBY

print "What is your name?"
your_name = gets()
puts "hello"+your_name+"welcome to Ubuntu"

Ruby (Improved)

puts "What is your name?"
name = gets.strip
puts "Hello, #{name}! Welcome to Ubuntu!"

Pascal

program Ubuntu;

var
name : string;

begin
    write('Whats your name?');
    readln(name);
    write(name, ',  welcome to Ubuntu!');
end.
